Sorry Janksy , but bananas immedialy start producing polen and pollinating the plant. try removing them if there's only two or five of them, but if they're coming up and there's many more than just a few of them, you've got a serious problem. Thing is unlike pollen sacks these are already starting to pollinate your plant ! be really careful removing them, heck even be careful moving your plant at all, personally i would put a black trash bag over it and throw it away if you have any other plants in the room, but the truth is, it's not the end of the world. Depends how far along you are, but make sure you stay on top of this situation, if you notice them spreading then just immediately harvest your bud , that will be a much better outcome than a fully contaminated/pollinated harvest. Sorry for the bad news, but it's the honest truth. Hope this helps ! 🚀
