get those cfls closer, 2-3 inches away max. try to get em as close as possible w/o heat from the bulb being an issue, with proper airflow it can be cm's away, thats how far from the top i keep my lights. are the ones on the bottom the mothers? switch them and the flowering chambers places so you can have enough room to flower. you should do some low stress training and fimmimg and screen of green to make it shorter and the amount of light you have be more efficient since its not only hitting your top cola and kinda wasting light, its hitting all of the new main growth points(colas) and turns em into all top colas basically... nice setup. your flowering chamber is in need of some more lights soon imo though.
