A few nanners in late flower no big deal if you are only running a few plants and they are in similar stages. Now if you have other lants that could potentially get pollinated early in their flower stage I would try to harvest soon. a few of my plants this year threw out a nanner or two late flower, it didn't fully herm on me, it was just telling me she was done. I never found any more nanners after i harvested and trimmed, and no seeds. my outdoor though i found a few seeds but no nanners so thinking their was just pollen floating in the ai. a few seeds not really a big deal, and can be kind of cool to have. i got a single bonus seed form my lemon ak auto in intrested to germinate and see what it does
