It looks like the leaves are curling down and are shriveling up. what is wrong?? thanks for the help i appreciate it. btw do u think i should use some nutes? or is it too early? or like rooting stimulater or anything?

what kind of light are they under, and dont spray anything on them(water bug spray etc..) those pics are so damn big they hurt my ''red'' eyes,lol

they are under 2 cfls. is that an issue
