Possibility, but some strains just make fat flowers at internodes. You'll know in a few weeks. Nothing you could do anyway. If a plant gets "bananas" on a few of the buds it usually only results in a very few seeds anyway. I just leave the plants, try to pick them off if I see them. If it does throw nanners then you'll have to find another plant that doesn't. I've grown different strains side by side in the same chamber and some got nanners others didn't. Just don't take cuttings from the ones that throw nanners.
