Hi
@Ge252! Hard to say without closeup pictures, but I think what you see are just the pre-flower calyxes, each stem has its own single calyx at the bottom of the branch. Do you see a pistil coming through this "green ball" ? If so, you're good to go. If this evolves and turn into bananas, you can gently remove the pollen sacs before they open. Hope this will help, keep us up-to-date and happy growing 👊
