I cant see any pollen sacks yet... sometimes you need to wait a few weeks into veg to tell. For now i cant really tell. Also the lighting is in the way. Can you get one of just the green plant
You wont know 100% untill you flower (12/12), you can cut a clone and flower it as soon as it catchs roots to see your plant's sex, i generally cut a clone from the bottom since i lollipop my plants anyway
