Hi I`m finishing up my grow of Wonder Woman from Nirvana. The plants are roughly 7 weeks old. They are slowly filling out, while the hairs and just growing crazy, close to 3/4 inch from the buds. I have the plants probaly 1-2 inches away from 4 40w cfls. The hairs growing to the sides, and the hairs from the lower nods are growing fine. However the hairs from the top of the kola are a third of the length and look to be just dissappearing or burning off from the lights. Is that even possible?
