Ok, I admit, I'm a newbie but I've done a lot of studying. I went to a grow class that a local farmacy put on after I was well into flowering with 4 OG Kush plants and 2 super silver haze clones that I got at the Hollywood farmacy. The 2 ssh clones were twins. Beautiful and big. After vegging for 3 weeks they really seamed ready so I put one of them in 12/12 for flowering. She was in there for 5 weeks. Had a super growth spurt in fact I had to bend her because she was getting to close to the sodium light. After 6 weeks, I decided to put her in with her sister. Now they've both been in there for another 3 weeks. The one that I put in there second got bushy and the leaves looked more like a cross between the Kush and the SSH but the flowers were looking good. Yesterday after 4 weeks I noticed that the second one had gone hermie on me. I wasn't checking because that seemed impossible. I immediately took it out of the room, put on some gloves, got a razor blade and performed a sex change operation. This morning I saw that there were more so I gave up and cut it down. My questions are:
#1. Why did it go hermie. Same conditions in fact it had more veggie time which should have been a good thing.
#2. How worried should I be about pollen?
#3. Should I hang and smoke the flowers on the hermie plant?

Thanks in advance for any help you can give this newbie. I've worked really hard and this is discouraging.
