      • I had to transplant after it got knocked down and now it growing unhealthy and im dont know what to do. Its my first plant and its been in the veggie stage since August. Its an indoor plant. I would keep it in my back room but its cold and my timing of planting was way off……. I think. My plant needs help

    2. This article works equally well for my tomatoes and other veggies! Used it during my winter grow to prevent infestation in my ladies, my WW and AK-47 came out good! Considering the trials and tribulations I put them through, your seeds produced plants that managed an exceptional harvest. Thanks Robert for all you and your staff do for us growers!

    4. Lee and Jo, I advise you all to download and read our free grow bible. Nutrinet burn is when the solution or soil mix is too hot fore the roots, and burns the plant down.

    5. You should always flush your plants if you are sure it is Nutrient toxidity, (nute nurn). I advise you all to join the support forum. This will get you faster response to your questions; Especially in an emergency!

      In order to not cause a “toxic” event in your grow; Make sure to supply yourself with the proper PH, and EC/TDS meters in order to control the grow environment of you plant.

      • mowerman,

        2 immediate serious issues come to mind.
        1. 1000 watt lamps are too powerful for seedlings. They can be used by expert growers at a safe distance. 32-36″. Maybe higher for seedlings. Temps, and humidity play a factor.
        2. Never apply nutrients to a seedlings. There must be 4-5 alternating nodes; Or, 4-5 trues sets of leaves; Proof of an established root zone.

        I question your idea to use Flora grow, and Micro alone. I have never seen this, and I used GH flora 3-part for 5 years. In early stages of development, plants develop stronger root zones with the application of potassium. So; Bloom would be better than Grow and Micro…

    10. Hello to all growers and future growers,
      just one comment and one question:
      The price for your seeds is NOT as important as customer satisfaction and support from a company that stands by there product and guarantees your shipment like these folks do !!
      look around at the competitors guarantee and you will see what i am talking about. my first order got snagged by the authorities. these guys re-shipped asap with no question. i was so impressed that i don’t even bother looking elsewhere ! do your self a favor and spent a few extra bucks and get the feminized seeds and no worries about male plants. even if you only got ONE OUNCE from a plant…that alone would be about a $300.00 value right there and you better get more than that or go back and read growing for Dummies…LOL. every seed i use has germinated so far without any problem.
      I have just one question to ask please. i live in an RV and had enough room for one 2×4 grow tent. i would like to be able to have some vegging while others are flowering. cant do that in the same tent obviously.
      can i veg my plants outside of the tent in normal day and night lighting as long as i provide the plants with high intensity 24 hours a day lighting closely above the plants and then move them into the 12 12 flowering tent when i harvest the ones that were in the tent ? secrecy is not an issue for me where i live and not afraid to have plants vegging outside of the flowering tent.
      PLEASE…i need the answer from a reliable source before i do something stupid and wasteful.
      Thanks in advance for any advice that you might have and good luck to you other new guys like me.
      Thanks again…Vern

      Reply
    11. No. Sorry brother, but you cannot flower and veg in the same room. I also believe I answered this question on another page.

      You never want to keep plants awake for 24 hours. 16018 hours of light is best for vegetative cycle, and 12/12 for bloom. Plants need rest just like human beings. Want proof. Read the ingredients on your multi-vitamins. Now; Read the ingredients on your high quality nutrients. You will find them surprisingly similar. 🙂

    13. […] Symptoms of underwatering include wilting, improper growth, and a lack of moisture in the soil. Although it happens less often than overwatering, it is still a serious problem that could negatively impact your seedling. It happens especially with beginners who have been warned – ‘never overwater your plants,’ so they overcompensate in the opposite direction. […]

      Looks like your nutrients or fertilizer is too hot. This can also be caused by PH being off. I suggest you join our Support Forum, and fill out a “Support Ticket”.

    15. Hey everyone. Awesome symptom checker btw. Unfortunately I cant find anywhere what is wrong w my plant. I have 2 Northern light trees, same everything, simple potting soil and no food added yet. So one of them suddenly has black coloration in the center of the growing flowers and slightly purple leaf stems. Hope someone has seen this before. Thank you and have a great day.

    17. I have 4 week old plants of various types growing indoors under a solar storm 440. They sprouted fine, grew to about one inch and a half and then quit growing. They are still alive putting on new leaves but they haven’t grown any taller and the leaves are tiny. I’m thinking that it might be bad genetics. I need some help.

    18. Please help me out..
      I had grown 13 plants in a space of nearly 200 cm2 by planting them in last week of August where they were good and GREEN. Till September 20 they were flourishing well but one day suddenly 2 plants were like dying after being 40cms tall. I got panicked and went to see ..when I slowly pulled they easily came out..
      My god I saw the stem and the skin was detached from the main root by some insects who ate it inside the soil…
      It thought a while and applied some neem leaves crushed water with salt for hopeful result. obserbed but same happened again.plants are sloely dying.. From 13 now 6 plants only survive presently. I am so desperate. Please help me out.
      I would like to send the video and pic of the situation.how can I do that.. I am in South India in AP where red sandy soil exists and the tclimate now is humid rainy and Lil sunshine..
      Please someone respond asap..
      With best wishes

      • Sounds like it could be fungus gnat larvae. I had 3 of 7 ww die because of these little bastards. The larvae eat fungus and other like material in the pot and when all gone, they start to work on the roots. Stop wasting. Let the soil dry completely( May take a week or more) and sprinkle a later of salt free sand on top of your soil. This creates a barrier that the larvae cannot escape from. Trapped and with nothing left to eat,they will die. Good luck. Don’t use bonide. Unless you wanna taste it with every hit.

      damp and little sunshine is not a good climate for cannabis plants. There are so many reasons this could be happening.

      Reply
      • rip,

        Again; It is hard to say without pictures. Repotting and replanting outdoors after you start the flower period is not recommended. Thewy could be getting too wet, or not have enough nutrients available to them.

        Best if you join our support community and tell us exactly what you have done. Too many variables in your case to give you an informed answer. Sorry 🙂

    22. How you ever come across lack of dankness? Grew 4 different strains together from 3 different seed breeders. All 4 had very little smell if any. Literally zero dank, just a very mild citrus in 1 and a mild vanilla(ish) in another. Other 2 just smelled of a generic garden plant (not 420). 3 of the 4 smoked fine, just no taste/smell. Couldn’t be just bad luck with all of them, could it?

    48. I’m growing outdoors in Hawaii. Sometimes just before harvest I come out to find a whole branch has ‘crashed’ literally overnight. Bud goes from green to brown and leaves wilt. Can you offer an idea of what’s up? Thanks so much. It is heartbreaking to see a beautiful plant develop and then slowly go down a branch at a time.

      • I’m not an expert, otherwise i wouldn’t be here reading up on plant problems, but i have dealt with something very much like what you have described. It happens very quickly, the leaves in the effected buds brown and die off and the bud looks brownish. If this is what’s happrning to you, it sounds like “bud rot.” At least that’s what has happened to me before and it’s devastating! It happens so quickly and the only thing to do is cut off that branch and hope it hasn’t spread to other buds on other branches.

    60. My plants have been in flowering stage but I have noticed the leaf tips have turned yellow and some are even dry and crumble when touching. I have just one out of the five have yellow freckles on the leaves, but only on parts of the plant ,not on all leaves ! I have raised the LEDs light away thinking it was light burn but its been a few weeks now and there’s no change .Can someone please help. Also mostly all the leaves are curling down

    62. hi Im new to growing out doors im growing (moby dick and tropical berry) in mother earth ground swell using general hydroponics nutes. I have 14 plants in a mix of 3 gallon and 5 gallon fabric pots. my leaves are curling and clawing from the outside in and becoming brittle., Ive added Armor si Silicone to my nutrient regimen. every other day they get Floranova grow, cal mg armor si. The outside temp has been over 100 degrees alot. 9 plants are not affected the five that are exhibiting symptoms are the same strain I can tell that. I have wheeled them all into the shade it didnt change anything the five plants started having this issue at the same time. I didnt have any problems with these plants until a weeks ago
