Bananas on the 4 week of flowering??

You referring to the female parts with brown pistols sticking out or the stipules I don't see anything wrong here

 

I see no indication of male parts.

 

Those are female pistils like the rest of your plant goodle search male plants and you will see a noticeable difference
