This may be your problem:
Nitrogen Toxicity
Problem: Dark green leaves, weak stems, and overall slow growth. Marijuana leaves that are nitrogen toxic often get "The Claw" or talon-like leaves that are bent at the ends. They also do an odd curving (or cupping) that is often mistaken for overwatering, but is unique to nitrogen toxicity. You can see a "clawing" leaf pictured to the right and more pictures below (click each picture for a close-up).
Leaves that turn into claws often start turning yellow and dying if the nitrogen toxicity is not treated, much like a
nitrogen deficiency, only the leaves will continue to get more and more clawed. Leaves eventually turn yellow or brown and fall off. You can tell if yellowing is caused by too much nitrogen because the rest of the plant will be dark green, and the yellowing leaves will turn into claws first.
The majority of times that growers encounter problems with nitrogen, it's from giving too much of it to their plants.
