Howdy!
Some hints!
With CFL and Flourescents you'll be wanting to keep the light close as possible, within 2-3 inches if you can get it there. This will help stop your plant stretchin.
Next, re-pot that sucker and bury it up to it's first set of leaves, this helps keep your plant a little shorter for it's space and it will grow more roots from the stem you bury. Or next time start your plant in a solo cup and slowly move it up to larger and larger containers AFTER you see roots poking out the bottom of your container.
As for whether or not this is male or female we can't tell from your pictures. The easiest way to identify gender is to switch to a flowering light schedule and see if it produces pistils. If you keep it in veg it will also show it's sex after three to four weeks if you're lucky while it's still in veg. Google cannabis pre-flowers to get some ideas of what you're looking for.
