Beginner Gardening: Twisted tomato leaf?, 1 by jmc1987

My tomato starts have been coming along great and looking quite strong, although i woke up to something interesting, several of them have....all i can describe as "twisted", their leaves, one of them even completely flipped upside down. I keep them in my southern window with the blinds twisted open, and a full spectrum CFL bulb to supplement. I just wonder if that is too much for them? or if it is too much water / not enough water? Craving a specific nutrient? Disease? (heaven forbid), or is this a normal behavior?

Thanks!
