Buddha, i would say that you have your lights to far away from you plants becuase that thing is really stretched, if it is a flourescent bulb it will stay very cool and you can put it as close as a couple inches away from the top of the plants, you dont want it growing for the stars. Also thank you garden knowm, they have not shown any signs of sex yet, and i cant judge any males or females, plants are only about a month and a half old, i think they might need more time, let me know what you think.
