my female hydro has hairs and ???

I have started to notice that one of my girls have started to grow what look like maybe flowers? I will have to take some pics, I had the same problem with my outdoor plant as some may recall, but after a few weeks the bannanna looking things ell off and have not returned. But these do not lok like bannannas, but very similuar to a males flower start?? could that be a sign of maybe a he/she plant? if so do I need to kill it like I had to my male, or can I just get ride of the flower looking things before pollen happens?
