This growing schedule is designed to be used starting in the first week of the vegetative phase for people who are growing in soil that was already fertilized when purchased. If you are at the very beginning stages (germination, for example), then you should start with this article about germinating and then return to this growing schedule.

It’s a good idea to read through the entire schedule so that you can see what to expect in the future weeks to come. If you are growing in a medium other than soil, check out our other grow schedule about Growing in Hydro

All images in this article are powered by Bergmanslab.com, my online cannabis training course.

I used the following items for this setup:

  • 48” x 48” grow tent
  • 9 White Widow seeds
  • 4-gallon containers
  • Gold label special mix soil
  • Flower Power nutrients
  • One 400-Watt MH light (for the vegetative phase)
  • One 600-Watt HPS light (for the flowering phase)

Week One of the vegetative phase

Amount of light: 50% of the lamps on (MH)
Light distance between lamp and plant: 40 inches for 400-Watt lamp
Light duration: 18 hours per day
Temperature during the day/night: 73/64 degrees Fahrenheit
Humidity level: 70%
Watering schedule: 250 mL per plant, every other day
pH level: 6.2
TDS/EC: —

This first week is all about your young plants getting acquainted with the strength of the light. If you have more than one lamp, only have half of them on for this first week. Using an MH lamp is best for the vegetative phase because they have more of the blue and white light spectrum than an HPS light, which is what plants in this stage need.

Be sure to always keep a close eye on the temperature and humidity, checking it every other day at minimum. The pH level should also be closely monitored, kept between 6.0 and 6.5. The pH level is how acidic or alkaline the water is, and it has a strong effect on how your plant’s roots are able to absorb nutrients. In other words, it is critical.

When watering your plants, give them enough water so that some begins draining from the bottom of the pot. Then stop watering and wait until all the water has been used up by your plants. If the pots are bigger than four gallons, make sure to feed them less water, as overwatering can happen very easily in a larger pot. More about this subject in my article “Watering marijuana plants

Water them every other day after that, but you will need to vary the amount of water according to a variety of different factors. This includes temperature, plant size, humidity level, and so on. Do not feed any nutrients to your plants yet because they are still using up the nutrients originally included in the soil. You should keep spraying your plants daily to maintain healthy humidity levels.

Week Two of the vegetative phase

Amount of light: 100% of the lamps on (MH)
Light distance between lamp and plant: 20 inches
Light duration: 18 hours per day
Temperature during the day/night: 77/64 degrees Fahrenheit
Humidity level: 70%
Watering schedule: 500 mL per plant, every other day
pH level: 6.2
TDS/EC: 500/1.0 (FP Start)

Turn on all of your lights for the second week of your marijuana plants’ vegetative phase. Move them closer to the plants as well (20 inches above them instead of 40 inches), but hold your hand underneath the light to make sure it’s not too hot. If it’s too hot for your hand, it’s too hot for your young plants.

If need be, you can transplant your marijuana plants at this point. The bottom of your pots will be the indicator: if roots are poking out from the holes in the bottom, it’s time to move your plants to a bigger pot. Read my article “How to transplant marijuana plants” for more information

At this point in the vegetative phase, you can start giving your plants some nutrients. Use Flower Power Start or another type of nutrient that is high in nitrogen.

You can also start topping or fimming your plants during this week of growth since they are mature enough to handle it and young enough to grow significantly afterward. Do the proper amount of research before attempting any pruning technique and read my article “How to prune marijuana plants“. Pictures below are just an example, I didn’t prune these white widows.

During this week, you should also place a fan in your grow room and aim it right over the plants, so it’s touching the tops of them a bit. The plants should all be moving in the wind a little bit, as that helps to strengthen their stems.

You will know it’s time to begin the flowering phase when the leaves of your plants are touching each other, leading to a green blanket of sorts when looking at your plants from above. There should be no light hitting the floor (since that’s just a waste of light).

Week One of the flowering phase

Amount of light: 50% of the lamps on (HPS)
Light distance between lamp and plant: 20 inches
Light duration: 12 hours per day
Temperature during the day/night: 77/64 degrees Fahrenheit
Humidity level: 60%
Watering schedule: 1 Liter per plant, every other day
pH level: 6.2
TDS/EC: 600/1.2 (FP Grow)

“Cannabis is photoperiodic-reactive; flowering can be controlled with the light and dark cycle.”

Jorge Cervantes

You will begin the flowering phase by lowering the light duration from 18 hours per day to 12 hours per day. This makes the plant “think” that fall is on its way, causing it to begin the flowering phase.

You won’t see any flowers or major changes for a few weeks still, but be sure to stick to the schedule because changes are happening.

It is at this point that you should switch to the HPS lights. As opposed to MH lights, HPS lights have more red and orange light, which is consistent with the right light spectrum for the end of summer and beginning of fall season. Therefore, they are best for this stage of your plant’s growth.

Even though your plants are now in their flowering phase, they will still be growing and using lots of nitrogen, so make sure the nutrients you give them are the same as before — highest in nitrogen. Once the flowers begin developing in future weeks, you can change up the nutrient regimen.

Aim the fan so it’s blowing the space between the plants and the lamps. This helps the hot air dissipate around the room. Before you water your plants again, make sure the soil is a bit dried out first.

Feed your plants from below by spraying an inch of water onto the base, where the roots will reach and grow faster.

Keep a close eye on temperature and humidity. Check your plants often for any leaf changes (discoloration, damage) as that could mean there is an infestation, a nutrient issue, or a watering issue. All of these issues need to be addressed as soon as possible, so it’s crucial you keep a close eye on your plants.

Week Two of the flowering phase

Amount of light: 100% of the lamps
Light distance between lamp and plant: 20 inches
Light duration: 12 hours per day
Temperature during the day/night: 79/67 degrees Fahrenheit
Humidity level: 60%
Watering schedule: 2 Liters per plant, every other day
pH level: 6.2
TDS/EC: 650/1.3

At this point, you should stop topping your plants, but you can still do other forms of pruning, such as removing the side shoots from the bottom of your plant, allowing the plant to maximize its resources on the other shoots, leaves, and buds.

You have likely noticed that your plants are growing very quickly. For that reason, be sure to measure the distance between your plants and the lamps every other day and adjust as necessary. You can see signs of your plants getting too warm when their top leaves are curling or becoming discolored. If that happens, raise up the lamps or turn up the extractor.

The TDS should increase by 50 every week, and the EC by 0.1. Watch the plants’ reaction when you make these changes, and rinse the soil after this week so you can switch to a nutrient regimen that is highest in phosphorus at the beginning of week three of the flowering phase. To rinse the soil, simply water your plants with water that is at a 6.5 pH level and has no added nutrients.

Week three of the flowering phase

Amount of light: 100% of the lamps
Light distance between lamp and plant: 20 inches
Light duration: 12 hours per day
Temperature during the day/night: 79/67 degrees Fahrenheit
Humidity level: 60%
Watering schedule: 2 Liters per plant, every other day
pH level: 6.0
TDS/EC: 700/1.4 (FP Bloom)

You should start seeing the beginning stages of flowers developing on your plants during this week. They will start as little hairs that will develop into balls with hair on them — these will eventually turn into actual buds. The plants are now using all their energy and resources for bud development.

Keep the temperature, humidity, water, and nutrients all at the right levels. Monitor all of this closely, since this week is when the number of buds is determined — that makes it a very important week.

Healthy plants will produce more buds.

Your plants are going to need more phosphorus now that their buds are starting to develop. Use a bloom fertilizer (like Flower Power Bloom) after rinsing out the soil. This allows your plant to absorb lots of phosphorus right away, which leads to a good foundation of growth for their buds.

Your marijuana plants are now at the point where they are consuming the highest amount of water. For that reason, be sure to keep the soil moist at all times, and feel in the middle or bottom to see that it’s remaining moist there as well.

Hopefully you have already removed the male plants (if you’re growing with regular seeds); otherwise, they will fertilize the females and cause those female plants to develop seeds rather than buds (therefore lowering the quality of buds).

Week Four of the flowering phase

Amount of light: 100% of the lamps
Light distance between lamp and plant: 20 inches
Light duration: 12 hours per day
Temperature during the day/night: 79/67 degrees Fahrenheit
Humidity level: 50%
Watering schedule: 2.5 Liters per plant, every other day
pH level: 6.0
EC: 1.5

You will start to notice the hairy balls starting to increase in size, perhaps beginning to resemble actual buds. You will also see little buds forming at the base of the marijuana plants. Keep an eye on the distance between the lamps and your plants, ensuring that your plants are getting tons of light but not so much that they burn. Use your hand to check the temperature.

Keep monitoring the humidity and temperature, the leaf color and shape, and any indications of bugs. Anything at all that seems strange should be checked right away with my online symptom checker.

Week Five of the flowering phase

Amount of light: 100% of the lamps
Light distance between lamp and plant: 20 inches
Light duration: 12 hours per day
Temperature during the day/night: 79/67 degrees Fahrenheit
Humidity level: 50%
Watering schedule: 2.5 Liters per plant, every other day
pH level: 6.2
TDS/EC: 800/1.6

You will see significant bud growth during this week. Make sure there is still plenty of water for your plants (they will still be using tons), and that all the other environmental factors are kept perfect.

Your plants may start to need some external support, such as plant sticks. This is because their buds will get so heavy that it might start affecting the plant itself. Don’t let them fall over!

Keep the fan going (rotating) to keep the flow of air constantly moving. You don’t want any spots of hot or cold air to be stuck anywhere, as diseases and mold can easily develop in those places. Air flow also aids in the movement of carbon dioxide, which your plants need plenty of.

Flush your plants with water that is at a pH level of 6.5 at the end of this week. Don’t include any nutrients. You will begin boosting your plants with a new nutrient regimen next week.

Week Six of the flowering phase

Amount of light: 100% of the lamps
Light distance between lamp and plant: 20 inches
Light duration: 12 hours per day
Temperature during the day/night: 79/67 degrees Fahrenheit
Humidity level: 50%
Watering schedule: 2.5 Liters per plant, every other day
pH level: 6.2
TDS/EC: 850/1.7 (FP Bloom + FP Booster)

Your plants are going to need more potassium to ripen and harden their buds, so you should add in Flower Power Booster to increase the amount of potassium they have access to. This will have a positive effect on the marijuana quality and quantity as well.

You will begin to notice the pistils turning from white to orange or brown in color. Keep an eye on these, as they will indicate when you should harvest your plants. Once about 80% of the pistils are brown or red in color, the harvest time has come.

Besides that, you won’t notice too much happening from the outside. You need to maintain the environmental aspects to keep the perfectly healthy environment for your plants. Also, keep a close eye on your plants for any signs of mold, diseases, or pests.

Week Seven of the flowering phase

Amount of light: 100% of the lamps
Light distance between lamp and plant: 20 inches
Light duration: 12 hours per day
Temperature during the day/night: 79/67 degrees Fahrenheit
Humidity level: 40%
Watering schedule: 2.5 Liters per plant, every other day
pH level: 6.2
TDS/EC: 750/1.5

The buds will still be increasing in size, and they will also be ripening more. You can expect lots of resin, as well as dense, heavy buds to come out of this week’s growth. The pistils will continue browning but remain patient, so you don’t harvest too early (as that would have a negative effect on the quality of your weed).

You might begin noticing that the bottom leaves start to yellow and die, but that’s normal and nothing to worry about. Keep feeding your plants the normal amount of water. Lower the amount of nutrients you’re feeding them by a bit, then flush your plants out with water (pH 6.5) towards the end of the week. Don’t give them too much in the way of nutrients next week.

Week eight of the flowering phase

Amount of light: 100% of the lamps
Light distance between lamp and plant: 20 inches
Light duration: 12 hours per day
Temperature during the day/night: 79/67 degrees Fahrenheit
Humidity level: 40%
Watering schedule: 2.5 Liters per plant, every other day
pH level: 6.2
TDS/EC: 250/0.5

This is the week your plants are going to be harvested. More pistils will be browning, and your plants will be absorbing less and less water — both are indicators of your plants being ready for harvest.

Our free little Harvest Guide will help you determine the best moment to cut your plants. Download it here.

Lower the EC dramatically, so your plants won’t have the nutrients in them at the time of harvest. For the last few waterings, only give your plants pH 6.5 water without any nutrients at all. This helps rinse out the soil as well (meaning it could be used for another round of plants).

Keep a close eye out for bud rot. Brown leaves will be growing from buds with bud rot, and they will come off extremely easily if you pull on them gently. Open the buds gently to look inside. If there is rot, take the bud off of the plant right away. Be sure you’re wearing gloves and make no contact with the other buds (since it spreads very easily).

Here is a little picture gallery from the harvest. The yield was 18 ounces (505 grams) so not bad at all. Please leave questions or comments below in the comment section.

      Actually, when the buds start to get crispy, you should put them inside brown paper bags to allow the inside of bud to dry as the outside has. After one day, you will find the crispy part of the bud […]Read More

    My question is whether or not it is appropriate to continue spraying the plants with water throughout the grow, as I do not want to facilitate bud rot. Thank you.

    Ben, I do not suggest spraying the plants past seedling stage, unless you develop an issue that requires a foliar application to resolve the issue. Happy growing, :)
