Looks kinda like a male to me,, but wait another week to be sure. If u don't see any white pistols coming out by a weeks time from now, then i believe it's a Male
Too early imo.. i have 2 closet plants.. they both preflowered.. one had calyxes w pistils... the other.. calyxes no pistils.. and took almost 2 weeks for pistils to come through finally.. .. although.. yeah.. that seems very round soo id be careful.. it very well may be male.. but always give it a little time..
Although it looks to have the classic "claw" pf a male preflower, I've been fooled before. Give it a bit.
If you look closely at the 3rd pic you can see pistols. I would cautiously say female.. wait another week to 2 and you will have more clear signs of sex
