If I were you after you transplant into seperate pots I would flower them. That way you will know if they are female. If they show white pistils they are female. If they show clusters of balls they are male. You probably already knew that, but I told ya just in case you didn't know. If they end up being female you can then decide wether you want to continue flowering, or switch back to veg to get them a little bigger before flowering again. Hope this helps
