In the second pic it looks like your leaves are turning over trying to protect themselves. I'm not an expert at all but this happened to mine because I had 8 cfls far too close. Think I over did it with the lights! Firstly I had bad burn because I read somewhere saying that cfls can be kept as close as 3/4 inches, so I backed them off about 2ft. Even at that height my leaves were turning over so I popped them to the top of their tent which is another 3ft or so. They seemed alot happier and grew much better no curling or burning. How close are your lights and how much heat are they getting?
