Hey dabman, yes, your babies look a little stressed!! I'm a newbie myself, but I can ask you some questions, anticipating what the expert growers might ask: What do the roots look like? Are you letting the pH fluctuate between 5.6 and 6.5? PH might be a little low. In my hydro setup, I let it fluctuate 5.6-6.4. You'll get some help soon, so hang in there!!!
