I just found this on my plant, only on the top, is this mould, this part of the plant is directly facing the fan, please what is this and how can I fix it?
Yes. You have powdery mildew all over your plants which is a fungi like mold. Those lights can't grow cannabis. You need to invest in a proper grow light as well
Mildew mate Neem oil will be your best but mind the buds! Also, as fore-mentioned, that light will not take you to harvest You will need to step up your game mate and invest in a decent light 150 true watts per plant min IMO
I would personally start over mate With a decent light ! If you do treat her, remove (carefully) any effected leaves Keep soil moist and keep good (better!) ventilation Good luck
looks over/under watered, see how the leaves are clawing down..... could be from the mold but im not 100%. it could be wind burn, but wind burn also can present in a bunch of ways. and i am assuming this is your first grow which makes me think you may be over watering..... but due to your lack of details about your grow, i am shooting in the dark as well
Nothing major. Some people like nitpicking. I see a little N claw but its nothing to worry about. What nutes are you feeding and at what doses?
White Powdery Mildew on Cannabis Plants - Identification & Solution! Don't start over. Spray them with a water/hydorgen peroxide mix or one of the options listed in the link above and do a budwash after you cut them down. Neem isn't available everywhere anymore. It's completely banned as a pesticide in some countries and states.
I'm curious what your ventilation setup is. PM shouldn't happen with buds that loose and a big fan blowing on them unless the humidity is really high.
I dont see any powdery mildew i think you are trying to flower under lights that are not powerful enough and what your seeing on the leaves is tricomes from the plant flowering. but just what i see, do you have a pic of the whole plant?
looks like a very heavy leaning sativa strain so you will be fighting pm for a while before the plants are done. Basically you will have to treat them twice a week to keep the pm from over taking the plant. People say ya cant grow bud with thos lights and I guess what they really mean is you won't get much yield or quality. Personally id prefer baking soda over neem oil to treat pm
He does need more lighting but I would be skeptical about the $$$ being spent on lights. Ive read countless threads like this one where the poster is convinced to go spend hundreds if not thousands on lights when its barely their first grow. This is the perfect situation for a blurple imo.
oh for sure I went cheap on my 1st grow just to make sure I could get to harvest. Dunno his situation but the plants already in flower and already needs to be treated , as this point he could just take em outdoors during the day for free sunlight and back in at night , good way to treat the pm and hose down outside while he is at it
