The pics are a bit too blurry to tell. Once you see white hairs though, you'll know for sure. You're plant may not show signs if sex until you switch the light schedule to 12/12 for flowering. Do you have any pics of the whole plant for my viewing pleasure?
Yeah my camera isnt that great.... like 2-3 weeks ago the plant was beat to hell with hail which is why some of the leaves look deformed, but it exploded with growth since and has created alot more lower nodes
but here are some more pics since u wanted to see the whole plant
Looks pretty good, though a bit stunted for its age. Are you feeding it anything? I noticed the soil is a bit sandy, and other scrub plants growing around it.
