That’s a female that was pollinated. Whether it hermied and pollinated itself I can’t tell, didn’t look at the pictures for more than a second
Males do not grow buds with calyx. They don’t grow calyx. Seeds grow in calyx. If there is a seed. It was female at one point.
Tell us. Feminized or auto? If they were feminized then it’s safe to say you made more feminized seed. And need to check for light leaks
Oh and my bad. I was commenting purely on the Pic directly above. Not the 100% male further above. Your friends seeds weren’t feminized, so your chances of male where 50%.
If planting non feminized seeds look for one’s with a flattish side with a dimple. These are seeds developed close to the stalk and generally have more time to develop/mature, which increases chance of being female. This method is actually pretty solid.
