found a banana growing from one of my girls

i found 2 little bananas sticking out of a bud on my shortest girl. i cut them off right away very gently, and checked over everything and havent seen anymore. i dont know if this is a reason for becoming a he/she, but it was forced into flower early, due to being planted later than my others. Only had around 2 weeks of veg before going 12/12. im actually surprised she came as far as she did, with some nice looking little buds.

now....im in my 8th week of flowering, i cut out nutes now, and around a week or so away from harvest. can any damage be done by letting the hermie go, or should i cut her down?
