i am no pro but i reed a lot and i think you can drop the light closer defiantly cfls they don't put off much heat at all i read 4 inches away with a fan works fine.
i have 1 300 cfl with many others and i made a dumb noob mistake of using mirrors so i don't know it all but i do know somethings about certain aspects of growing and cfls are very low temp compared to hps or mh-hid lighting. also i think you started flowering a little early. thats just me though not a fact.:jointsmile:
