Advice on selecting male and female plants ?

Hey 👋 I have about 25 Hindu Kush seedlings in red solo cups ready to transplant. I only have two lights, and 12 pots worth of dirt.

To give my self the best chances of getting a high number females, how would I go about selecting them at this point? Back ground: Half of the seeds sprouted first, those are generally the taller plants. Some have long leave stems and some have short leaf stems. I was thinking it may be an indicator but I wanted to see what y'all think before I transplant today. thx
