Sexy time help for plants Round 2

ok so the plants are 4 days older and i got some better pics of the preflower. I turned out that two are female, and there are two that im not sure of, I am leaning towards male but I want to get a secound opinion before i chuck them. I took these pictures through my photgraphers lense so there 10x magnification.

I'd say it's still too early to tell. Wait until you can either see the white pistils or it goes ballsy.
