100% hermie for sure. no question about it.

Looks like you have 3 other plants in that grow. My advice is remove the plant, check it all over for pollen sacks, and if its just the ones in the pick then remove them and put it back but keep a close eye on it. If more sacks are developing then get rid so it doesn't polinate the others.

Kill it.

go ahead and pluck what you find, but unless this is a single plant, throw it out if it continues to grow more of them. A little sacrifice to save the rest of the crop.

It unfortunately looks like your plant is hermaphrodite (male flowers and female). You can remove the male flowers and hope you find them all and that it doesn't produce any more, or dispose of the plant (that's what I would do). Yes, I know it's really unfortunate and annoying, but if you miss just one pollen sack and it spreads the pollen, you'll have 100 or even 1000 seeds in your plants. The pollen can also stay in the tent and pollinate your next plants, which obviously creates even more problems. Many say to leave them inside and only remove the ones you see, but believe me, it's better to be radical now than to regret it later.

Your plant is going hermie. Those are male flowers, you should rip them off and dispose. In same place you have usually single female calyx, so if you are not certain, dont rip in other places . But in first photo, its definitely male flowers forming ...
