Not a complete expert still a novice but that is clearly turning into a Hermie, I've been advised to sterilized the tups of tweezers with rubbing alcohol and them carefully pluck those banna like structures off where ever they are forming unless they are everywhere and then it's time to just chop her down or if its early in the grow and u keep seeing then pop up after plucking the few that are there 9 out of 10 times means itll stay that way, I had a female in full flower that started to do it because of a cold spell and I forgot to keep it warm enough but I plucked the 4 or 5 I found VERY VERY CARFULLY AND she didnt gimme any more problems or seeds and I was able to harvest her without issue
