Kinda looks like a dooder. Sorry. The pre flowers look up too far in the crevasse too be a girl plus I don't see any white pistils sticking out but might be that its not macro enough. From what I can see it looks like a dude. If it starts getting some buddies next to em its definitely a guy. Also look at the new growth. It tends to grow nodes in rapid succession real close when it starts to flower and if you look in there and see a lot of sacs its a dude.
No pistils yet but the plant is still very young. Only 4 weeks old , out of them one week it was stunned. Gonna wait a few more days, if no pistil shows up its done deal.
