First time growing photoperiod-too early to tell sex?

Got a random plant from a neighbor about 4 weeks ago. Been giving it 24h of light in the grow tent and it's growing nice. Can't for the life of me tell if it's male or female or if it's too soon to tell-picture attached.

Is this remotely useful in determining sex or is it time for more waiting?

Grown plenty of autos but I'm a bit lost at sea here.

I'd say female. Pics of more nodes, perhaps?

Looks to early to tell

I always check mine twice a night soon as you flip to flower it'll show then in about a week. Just stay diligent and you will know. That's what I do.I hope that helps you out. I am 97%sure what I have 1st week of flower.
