Is this a ball I see? [pics]

3rd day of flowering. Looks to me like a ball of pollen.

Well, if I judged your pics against this: https://www.rollitup.org/general-marijuana-growing/340683-sexing.html
I'd say yes, but wait for someone more experienced than me to give a definite yes before you chop him. If that plant is in a room w/females, I'd isolate him asap though just in case.

could be the start but its to early to tell give it a week

Its a calyx. Give it some time to fully sex it self.

What calicat said.

no its jus a calyx, she looks great....
