i raised it about 1.5 feet hopefully that works but i read that if you can tollerat the heat with your hand it should be ok unless that was for more mature plants.
 
your not giving it any ferts are you? In the last photo it looks burnt on the side.
That light is way to close, a foot and half or two. You should always start under fluorcents.
