Indoor Growing CFL lights plz help!!!

I have two plants that r both 12 inch or more under 3 regular 23watt flourscent light bulbs. And I have 2 13 inch flourscent night lights and 1 24 inch 26watt cfl in there. I can't tell the sex of the plant but both plants r healthy and one I had on my window sill that one is not as nice as the one that I started growing in my closet but there both in there now. They have leaves growing from between the branches I think it's called the nodes? But they aren't showing any signs of there sex. One kinda looks like it has a little tiny ball I'm not sure. There aren't any branches growing between the nodes tho.. i just switched the lights to 12/12.
1.Do you think it's enough light?
2.why can't I tell the sex at all?
3. how long do you think till it shows signs of the sex?
