my leaves are curling up real bad, and some are kinda droopy, they are in about 75degrees, they are under a 1000watt hps light, growing in rockwole cubes. Anyone have any idea what is wrong, any help would be appreciated.
Cutting edge... good man good man, that is exactly what I recommend everyone use. Out of curiosity where did you first hear about cutting edge? Because I had never heard of them before I went to california, but that was the #1 recommended out there, and now I have seen the results for myself and its great. With that said I doubt its a nutrient problem. Since it is only the top of the plants that are doing it theres a good chance its because either your light is too close and you need to move it back more, or provide better ventilation for the light so that there isn't too much of heat buildup. try doing one of those first and see if your problem stops
they are in rockwole, i water once a day.. it seems like they dont use too much water. Should i wait for the rockwole cubes to get completely dry, or is it ok to water when they are still kinda heavy with alot of water in them????
Sounds like heat stress to me, maybe raise the light up some more or add a fan to move some air. Since you only moved the light up a couple days ago they may not have recovered yet.
