Is this male or female?

I am worried I got a male on my hands. I am fairly new to growing, so I need some help!

It's been in 12/12 for about 10 days now. Are these pollen sacks?

male, sorry for your loss

Thanks for the confirmation guys.

Can I re-use the coco with a feminized plant or will that hermie it?

You can reuse the coco, just get rid of the roots, and give it a good flush to get rid of the nutrient build up.
