Sorry, those are balls... chop em!

Although... I had 1 plant that started out with balls, which I cut off with a blade, and then go full on female.

I'm currently finishing this plant and kept a CLOSE eye on her/him... (he-she?) and never saw random male flowers pop up.. but then slowly they started to diminish as more and more female flowers started to show. It may have entirely been that I stressed the plant too much (first grow) and it went hermie from the get-go but then laxed out.

So I'd keep an eye on that plant after ripping those balls off.
