Strange Hermie?

So I'm wondering if anyone else has ever run into this, because I never have.

I'm in the 6th week of flower using fem. seeds indoors, and everything was looking good. I went away for a couple days and came back to find that one plant was not only showing male flowers, but had also pollinated itself. So basically I had a plant that was female go hermie, have male flowers, and have seeds. I chopped it, but am wondering if anyone else has ever had this happen?

some fem seed will hermie in week 6 to 8 shows yellow bannanas and if u leave them u get seeds feminized ones imo and from what i have seen i have found that dutch master reverse works well for this problem i do it day one of flower then on day 10 and no nanners since

Thanks, I'll give that stuff a try
