I would take a cutting from each one and flower the cutting so you will know what you got. That way if one is a male you will be able to pull it and get more grow space. also this will identify the female. and you can make a few more clones from her and increase yield. this might set you back a little maybe a month buy you will have more. I have 3 going now and thats what I plan to do here in 2 mmore weeks.
