Uh... yes sounds like your plants are going hermie. However, it you are in the last two weeks it shouldn't be a huge problem as any pollinated buds won't have time to develop seeds. However, continue to pluck any nanners that you find and do your best to find them all. The bad news is that some will be buried in the bud which you will miss. You want water them for 2 weeks with straight water before you harvest to remove the fertilizers.
