It looks like cannabis 😄
Maybe 🤔😂
But seriously, you can't tell the sex yet.
Is it an autoflower or a photoperiod?
The stem still looks relatively thin, and the cotyledons are still present. Your plant is still very young. Wait a few weeks, then it will show itself on its own if it's an autoflower; for a photoperiod, it will only show after switching the light cycle to 12/12.
