Week five of veg when’s flower?

Hey guys and gals. I’m in week five of veg and she has grown quite a bit in the last week. Is this her veg stretch before flower? I can’t see any pre flowers. Flower should be soon right?

If she’s a photo, she will stay in veg until you flip the lights to 12/12. If she a auto, she should start soon

She’s auto. Forgot to say that

My auto starting showing pistils during week 6

She just started to and grew two inches overnight
