Hey Guys, My (hopefully) girls are about 3 weeks from seed in rockwool and hydroton with 16 23w CFL's on them right now. The pH is from 5.7-6.2 and my nutes are at 620ppm right now. I've been having some problems with the leaves drooping down and looking a bit unhealthy, although until recently there hasn't been much discoloration (beyond the occasional brown or yellow tip from getting too hot from the lights.) I'm attaching some pics to show you guys what i'm talking about. Also, the lower leaves on one of my boxes have started to dry out and crisp up (these are not main fan leaves, but the original three-pronged ones from when they were babies)
Thanks for any help.
