That's tricky. The location of the bud makes you think it'd be male. But it doesn't look like it's on a stem. Actually looks like a little calyx. I don't know dude, but you'll be able to tell for sure within a few days. Week at most. I will say this, you're gonna need more light. If that turns out to be a female, already vegged two feet tall and in a 5 gal, she's gonna be a big bitch! You'll need at least twice the light for that big girl. I say need, it'd be nice to have at least twice the light. But if it grows, and it's smokeable,and it makes you happy...
