Nutrient Burn In Marijuana Plants

July 3, 2021

It is unnecessary to give your plants an overabundance of nutrients for their health. Keeping it light is the best way to go for optimum growth. Nutrient burn is one of the most frequent issues newbie growers have, which happens when the plant’s roots absorb an excessive amount of bottled nutrients. Read this article and learn how to identify and prevent a nutrient burn in your marijuana plants

Marijuana nutrient burn

This overabundance of nutrients leads to yellow or brown burnt tips on the leaves. The amount of nutrients must be reduced, or else the problem spreads from the burnt tips inward causing the leaves to become crunchy and curled. For example, if there is too much potassium, nutrient burn will show up as brown spots near the edges of the leaf. When there is excessive nitrogen, the leaves will tilt/curl downward.

Bottled Nutrients

Usually you have nute burn because you are putting too many additional nutrients in the water. Always use nutrients that were made for cannabis plants. Remember, if it is good for tomato plants than it works for marijuana.

Be sure you are using the proper nutrients for the particular growth period your plant is in. There are different requirements for the vegetative and flowering cycles. By not following this appropriately, you could potentially be putting your plant in danger.

Hydro System 

One way to cut down on the nutrients in your water is to add pure, pH’ed water to thin out the nutrients. You can also try mixing a new batch with fewer nutrients in it.

Always make these changes slowly with hydro systems. With this system replacing the water and reducing the nutrients accordingly, will result in instant positive changes. The nutrient burn expansion should cease.

The tricky thing about hydro is that certain strains work fine with a different level of nutrients. Even if you give your plants the same quantity of nutrients, one may still get nute burn and the other may have a different level of deficiency. The plants take in nutrients differently.

Also, keep in mind that your plants will consume a certain amount of water based on the humidity and temperature in your grow space. To make things much easier for you when growing in hydro, use a tool called TDS meter to assist with manage the nutrients in the water. It will literally let you know the amount of nutrients in the water and make you aware of whether the levels are going up or down every time you look at it.

Nutrients during flowering stage

Nutrients during flowering stage

Flowering is the second phase of a plant’s life when they start producing buds. Marijuana plants are far more susceptible in the flowering state because they are unable to recuperate from any damage. Basically, the closer it is to harvest time, the lower the chances are that the plant will recover since it is putting all its energy towards making buds.

So, your marijuana plants require more tender loving care when it is in the flowering state. Don’t let the nutrient burn get out of control.

Once the plant is fully grown you will need to start thinking about harvest time. Our free little Harvest Guide will help you determine the best moment to cut your plants. Download it here.
