Sexing during Veg

Hey everyone, my grow is going very well, into 4th week. I can tell the sex already on all but 2 of my plants. The plants are very developed, growing crazy. Is it normal based on the development of the plant to see the sex? All I've read tells me that I have to wait till flowering to tell.

I don't think it's normal for plants to show sex in the 4th week of veg (in 13 hour days or better, of course), forgive me for being skeptical about what you think is identifying the sex of these plants.

Maybe you should post some pics to be sure.

ya cool, they wake up in an hour and I will get some fresh pics. thanks

My last plants showed preflowers in the fourth week of veg.
