you need more lite, they carnt even hold there self up never mind buds. get some proper lites, didnt you read up before you started to grow, you wont grow shit with them.
if your going to grow at least do it rite, you need 2 more flos for now, and then a 250 or 400 hps for flowering.
sorry for being so blunt, but your just wasting time/power, growing plants like that.
also do you have a fan. and what are you going to use for 12/12?.
