I don't know how many lights you have there.....i've lost count but it sure sounds like alot. Get rid of all of them except 2 cool cfls or so for a few days and keep the light about six inches or so above. They can't take tons of light at that stage. Also a weak or bent stem can be a sign of overwatering as well. Now if you had a photo we might all look at them and say it's normal...really hard to say w/out pics but you sure don't need a hundred lights on them at this age.
