No worries, it's too late to get any seeds. All you can do, is pick em off and throw 'em away. They'll keep popping up here and there, so keep an eye out, and try to catch them early. They don't release pollen immediately, so that's another thing in your favor. The only bad part, is that you shouldn't clone it, or you'll have those "bananas" again, possibly worse than this time. I had a sativa that did that, and I picked 'em off, cloned it, and ended up with a shitload, next time around. They come out earlier, too. I was tedious and picked every one of those off too(at least a hundred), and the smoke was awesome. I didn't keep it around though, too much work.
