You are going to need some new pots for flowering man, those big cups can't do the job . By the way they look, I would flower now to see the males from the females. They show sex between 10-14 days of 12/12 light cycle. You should wait until you know their sex before changing them into bigger pots so that you don't waste time and soil potting male plants ( MOst are always male ). You might just get lucky and have all of them be females. I hope u will have space for that . Keep up the good work, keep em green :thumbsup: ...
