Possible Hermie?

Definatly take that out of your grow room buddy. 100% hermie. Either unreliable genetics or stress can hermie them. Hermie weed is still fine just will contain seed after it pollinates itself so u can still grow it up just not around the others or it will pollinate them too. Good luck.

looks like a sac... not in first pic, unles you aretaling about teh sac at very bottom of image... not what it is focusing on.

Pic one is definitely female calyxes. Pic 2 shows in the left background something that looks suspiciously like a male pod forming. The fact that the pod in pic 2, the one in the foreground, has no pistils as yet, would have me worried. I am almost certain that yes, you may have a hermie.

Chill dude. That's a calyx. The white hairs indicate female. (Look for two) unfertilized calyx = sinsemilla = what you're looking for.
