m0useanswered grow question 3 years ago that looks like a complete pollen sack more so then a bananna coming out of a calyx.
You got a Hermi. :(
Are their any light leaks in your tent??
I would isolate that plant asap and check the others before any of the pods have a chance of opening.
in another room, place whatever lights you have on it. and wait till they open, If they open you 100% know its hermi and can kill it or let it do its thing.
Where did you get the seeds from? a reseller or direct from dutch passion, reach out to them and see if they can give you any insight.
Sorry for the bad news.
Good Luck
