Hey so I have a question, when u think I can sex these babies

Hey when do u think I can sex these?

Some strains aren’t identifiable until they are in flower but some will show sex at around 4 weeks of veg.

What am I looking for exactly and where

I don’t have an info graphic on my phone but just Google “cannabis sex” and a ton of images showing what males and females look like with come up. If there’s a cluster of balls at each node then it’s a male. If each node has a single teardrop with white hairs coming out it’s a female. If it has both it’s a hermaphrodite.

Alright cool thank you so much
