Thanks, everyone, for the info, but this was a while ago. My problem was partially ph because when I started adjusting the ph they started growing again and looking much better. The ph problem was being caused by the nutes that came with the system. They're dsesigned to ph balance the solution to 6.5. Basically, they're garbage for growing cannabis. I got new nutes, and watched my ph closely and they began doing better, but I had another problem as well. I had a serious bacterial infect. It took me a couple weeks to figure out that's what the problem was, and then it took me a couple weeks to figure out how to eradicate the bacteria, but I finally did. My res is clear now, and will stay that way, because I'm keeping it inocculated with beneficial bacteria and fungi and such.

They're doing much better now, and have been in 12/12 since Oct 3rd. One of the females was badly stunted by the experience(4th pic), and when the male and other female began growing quickly again the stunted one was so far behind that the lights were just too far away from her to be much help to her. I've lowered one of the lights down so that it's right above her, and she's doing a little better, I've begun seeing visable growth from her again.
