wow, the 12/12 is way to early, your getting to excited, go buy a bag and relax your not getting any bud within 2 months period no matter how much you go spend right now. Not possible! with that granted, lets talk about the 12/12- too early- you maybe able to revert back to 18/6 but you should have started at 24 and worked down in increments as the lamps need to be raised for their height. you shouldnt put your first load into veg until its 16-20 inches tall- I am currently shooting for 18, then you can clip a clone and go to flower. Your second problem is lighting- you need to give these plants some TLC- they need a room in the house, build them a small cabinent- your CFLS are low heat- and if you build it right you can keep all light out and flower.

At this point tho- it may be hard to revert your 12/12 and the droopyness... crazy furtz in your soil- you'd be better taking dirt from outside. try a mix or pearlite and sterilized soil- like 20% will make drainage alot better- that might help the droopyness

But that next seed lined up, work on her- and give her the TLC she needs
