Hello all, thank you for stopping by, any help is greatly appreciated. I have been trying to do my own research in identifying the problem and am thoroughly stumped.
I am an amateur grower with only 2 successful grows under my belt, and by successful i mean i got something to smoke out of it, no jaw-dropping yields. This time i wanted to do it right though, so i spent money on a couple nice lights, and decided to try my hand at hydro.
I am using a dwc setup, with botanicare cn-17 nutes, and aquashield. At this point i have only used the grow nutes and aquashield. Plants are about 5 weeks from seed and are clearly stunted. Temps are almost always right around 70-79, water temps are never over 65, usually 60 or under. Ph is very stable, i rarely ph down, always to 5.8 or as close as possible. I have ended up with a very awkward feeding schedule trying to figure out the problem. But even in the strongest dose they have never had more than about 1/2 to maybe 3/4 strength nutes. Possibly even less. recently i have also added a small amount of epsom salts.
Basically, problem is, older leaves ALWAYS develop several rust colored spots, then eventually completely brown, dry out to a yellower color, and curl up and basically die. New growth continues to be vigorous, leaves growing bigger and bigger each new set, then eventually suffer the problem as they fan out. Newer leaves were looking a little purple for a while, but that stopped after adding more nutrients.
The problem im having, is this is the second set of plants this happened to. I scrapped the first set almost as soon as the problem hit, as i wanted a fully successful grow. I assumed i had burned the shit out of them, since they were pretty damn young when they ran into trouble, even though i was only feeding them a very week nutrient solution. At that point they should have been able to live off of their cotyledons. So of course, it must be nute burn. This time around i went sooo easy on nutes its ridiculous. then, after initially doing better than the first set, they were hit with the same problem, with NO NUTES.
At this point, i was baffled, gave them some nutes to see how they responded. Plants grew a little more vigorously, an have now formed 4 or 5 new nodes since the problem first started, but all the fan leaves eventually curl up and die! This is very frustrating. The other day i decided it was time to see if this was nute burn or deficiency. So i gave them a pretty healthy extra helping of nutes. This bumps them up to about 3/4 strength if i remember right. For their size i thought this was far more than necessary. Of course, i see ZERO reaction. No better, no worse. Plants are still doing the SAME THING.
I have included pictures of everything i can think of. The new growth remains healthy looking, old growth looks horrible. PLEASE HELP!! i want to grow something successful!
