Sexing help

I haven't ever flowered a plant before, I know what to look for when sexing, but inexperience tells me I should have other eyes on them before I remove them. These 3 are 1 week into 12/12 cycle with 1 400hps and I have removed them this morning. Before I dispose of them, I just wanted confirmation. I'm still a little shaky with possibly confusing pollen sacs for new growth and just want to be sure. I'm fairly sure these fellows are male, but wouldn't mind your opinions.

Thanks.

good to know, these were the last of the batch that were showing these... guess I have all my mama's now. Thanks again.

Hey Guys, I thought I had caught all the males, and when I checked this morning, I found these. First and last pics are of what I think is a solid female, other two did have the female traits but have started these little sprout things. Problem is, I am having problems determining if these are seeds or new growth. I can only find pictures of matured flowering plants. Can you tell me if Ive been pollinated or if this type of growth is normal in the cola growth... also, can you clone a pollinated female and grow virgin girls off that clone or do I need to start germinating from scratch again?

The 3 in the middle look like either male or hermies, the pic in the very middle is male for sure.
