Hey there Starr, polen is crazy it can really come from anywhere, even your clothes, it could just be a genetic thing aswell, some phenos will just do that sometimes. I've seen really potent and tasty weed that had a lot of seeds in it, just harvest the seeds and grow them out if you end up liking the final product. As long as you're sure there are no bananas then you have nothing to worry about. Hope this helps ! 🚀
