Get those lights closer. They look to be about 5 or 6 inchs from the tops and can be even 1 inch away. Also the leaves look to be wilting a bit so maybe less water. Cfls won't get hot and make the water evapourate fast so if you over water you have a chance for root rot.
As long as you check your girls out every day you don't need to worry about under watering.
I'd say once you get those things done, keep it 24h light for a week and tell us how much they grow..
I'll bet they double in size at least
