Shit I cant even see anything... The pic and plant is to small for me to see pollen sacks or calyx's with pistils... you guys must have better vision than 20x20... In my opinion this is way to early to tell... But then again, maybe i'm just not seeing the picture as well as other? I'd give it more time... But if you infact see ball sacks, then it is a male.. Don't be confused by a swollen Calyx.. Theres times where ive seen plants that looked like pollen sacks, but turned out to be a very tiny bud forming instead.
