This is an Autoflower, Kings juice from Greenhouse. She got topped before flower. Not LST or anything. I'm worried it might be a pollen sac, because next to her are also two other plants. Thanks for the help :).
Good for you for checking the sex. You’re looking for 2 hairs to grow from the “balls” or calyx, at the node.
Pic 1 has no hairs and it appears pic 2 may have the hairs on the backside; hard to tell.
If you’re not showing 2 distinct hairs on the balls/calyx on the node above the fourth node you may have a male or a herm.
Best of luck on your grow.
If it is you have time for more of them to form before you need to worry. The first photo is definately a female calyx. Not sure if the second one is unformed of start of a herm.
