GHS Big Bang Hermi?

Hello I am fairly new to this site and this is my first go at a grow . I jut wanted to say that I learned more on this site in two hours then a week of surfing the net, you guys are awesome.

I started 10 GHS Big Bang fems, only 5 of them popped. I grew out the five for 40 days in veg and put them into flower on Nov. 23 (approx. 2 weeks in flower to date). Being it is my first grow I ran into a few problems such as, nute burn, overwatering etc. The plant was very forgiving but unfortunately the end result i think I got was hermies and/or males.

here are the specs;
1000 watt hps
monster grow 12-7-15 (grotek veg nutes)
5 gallon pots of nursery soil (pro mix "bx")
had a bit of ultra bloom for the first week or so of flowering (mirical grow 15-30-15)

Almost all of the plants showed male signs when I induced flowering. But I noticed what may have looked like a pollen sac were opening up into female flowers/pisols.
Soon it seems I can find both sexes on 3 of the plants and just male sexes on the other two.

Here are some pictures, let me know what you guys think.

P.S: It's all I have growing so I'm not going to "chop the crop"

They all turned into hermies? take a close up of the stem>branch

There sleeping right now so I cannot. You see the second last from the right end. That is a main top kola with a female flower on top and sacs underneath

Actually the third from the last is also a hermie. So pictures # 4 and 5 are def hermie (3 of them) and i have two others that are just like pic #6 that im pretty much sure its a male, I thought it was impossible to get a male from GHS 100% fems, only hermi's :S
