wow...that plant looks really skinny and sad. How close are your lights?? i'm not an expert, but it looks like you should add a lot more lights, especially around the sides. What sort of soil? i don't see a whole lot of perlite or other ammends in the soil, so maybe it's locked up? The soil needs to be "loose" so the roots can stretch and breathe. (Not "loose", per se, but certainly not tight and compacted.) How often are you watering, also?
If that's your only plant, try to bush it out with some lights and pray it's a girl. There are a lot of grow guides and helpful threads on this site, it may do ya well to check em out. Hope this helps!
