you might want to start flowering at the end of january atleast , those plants should be about 3 ft vegged , also those stems look flimsy , i just read your thread, because of overwatering and heat early in your grow , you should give them an extra 30 days to veg. also , don't go 3/4 yet , go 1/2 for a week or two then bump to 3/4 , i would suggest you get more cfl's to make the most out of the extra vegging time , also , consider getting a real light from htgsupply possibly one with a conversion bulb so you can use it for veg and flowering , 400w atleast , they only cost like 160
