Can you sex a plant during late Veg cycle

Is it possible for a plant that is in late veg cycle old to already be showing its sex. Because I still have my plants on light 24 hours and I can see the hairs already. Or what I think is the hairs. They are about 1/4 inch long.

yes sir thats how a lot of people grow they wait for the plant to mature and show sex and then flower

yes you can tell sometimes. are you sure your not seeing the stipules?

I pretty sure its the hairs, but I am a newb, so can you give me some ways to tell the difference between hairs and stipules just in case.
