Looks like a hermie or maybe it got pollinated and those are a couple seeds on top. Either way i would just pluck those little round balls off. If they are pollen sacks you dont want to leave them on there.
JUST BEEN TO WATER MY GIRLS. bOUT FOUR HAVE A FAIR FEW OF THESE but they all have brown pistils coming out of them, does this make any difference?
I plucked one off and in it was white mush.
