Haha well that's a relief. Moving on...
Oh yea man, she's a beauty just ready for you to give her some intense lighting to produce those sparkling, juicy buds.
Ok, let's have a look at what you have so far. According to your details, you have 2 Halogen lights above everything producing roughly 200w both. You also have 3 daylight bulbs above each plant producing roughly 120w for each plant. 200w + 120w we get roughly 320w/plant. I'm saying roughly alot because that's really what we have here lol. Ok, so you were giving them all roughly 320w of light per plant in veg. Now that you're entering flower, you're going to want to try to give them double that (or at least as close as you can get to double the light from veg). So to answer your question as to what I suggest, my answer is something close to 600w (or more if you can afford those 630w CMH fixtures). They sell some really nice CMH fixture kits with ballast and everything for roughly (lol) about $400 or so. I don't know your budget, but bottom line, I'd give your girls much more light than what you're giving them now. You're going to need it if you want those buds to really thicken up.
P.S.
They also sell some cheap (but good) LED's. Some for as little as $80 or so at Amazon. They have Veg and Flower settings and have full spectrum and all that juicy stuff. Might want to look into them as well.
