When to start looking for sex

Hello I have 2 seedlings growing currently and they are on day 15. I've been told they can show as early as 25 days. My question is when is the earliest in your guys exp your plants have shown. This is my first grow so if one is male but i get rid of it quickly will I still be able to keep the female?

The feminized plant i have going now showed at 3 1/2 weeks. I wasn't expecting to see anything there but the calyx was fully formed so
i don't know when i started. I'll start another seed of this strain sometime and see of that shows early as well.

some plants show in Veg if you veg long enough but usually 1.5 to 2 weeks it should show or at least all strains ive grown have

Yes you will be fine.

Ok so I'll post some pics later I think I see 2 hairs but I'm not sure.

Ill post the sex pics below...any help is appreciated!

the first two is of 1 and the second is of the other! i can get more if u need them

I think it's just a bit early from what I can tell....not long though prob 2 days or 3 at most, Good luck!! I have 3 going and not positive about sex on 2 out of 3, looks like 2 out 3 ain't bad....LOL ! Last grow only got 1 female out of 3 so anything will be an improvemnt over that disaster....then I cloned the female 2 times and they are going into wk 2 of flower First grow so feeling good!
