btw bro nice plants, they look nice and healthy. dont use clear pots/cups tho, roots hate light. i did that once to. u need to repot like LZ said.
flowering is either done by the sun around august. and i think january if u live down south.
otherwise indoors u do it manually, switchin from 24/0 or 18/6 to 12/12 and they usually "show sex" after about a week give or take. after they show sex u count from there til however long it takes for ur plants to finish usually 60days, give or take. check trics with scope is way to telll when to chop.
also depending how big u want them or get or how much room u have is when u switch to 12/12 hrs of light. avg. id say is about a month or longer, any sooner she wont get that big. they usually triple is Size when u switch to 12/12 so be careful. i flipped at 18inches..and it is almost 5foot now......hope i helped.
