Oh, feminized seeds have a high hermie rate. but the worst you should see is a hermie, not a male. Those are probally little pre-flowers that haven't showed the pistils yet. I had a very beautiful planbt that grew faster than the rest of my plants, but I thought it was a boy so I chopped it down and used it for cloning practice. Well, rooted 7 clones and decided to throw em out in the back yard. I went outside today, looked at one of the clones and it had pistils showing >=O
It was far past saving though..
