When does a seedling enter the vegetation stage?

I'm wondering at what point is a seedling considered to be in the vegetative stage. If it's after it gets the first set of true leafs would that mean one should start counting vegetative days then?

Actually its when the 2 cotyledon leaves fall off. When you think about it it's almost as if the plant is saying I don't need you anymore I can go out and be my own self. Like the plant is ready to face whatever may lay ahead. Just a little stoner talk from stoney.

Also i like to put mine into flower as soon as they wither away and fall off even though it's not really appropriate and most people will say don't put it into flower until the plant is showing sex which means it has hit sexual maturity but who has time for that? I need bud to smoke.
 
I've heard it's when the cotyledons fall off but I've also heard that they start veg when the first pointy or true leaves show up. This said, I've had cotyledons hang on and stay green over a month into my outdoor grows until they start turning yellow.

Generaly a week or so after sprouting, or once the first set of "true" leaves start coming out, which is when the plant switches over to photosynthesis from living on stored reserves. Some plants can even photosynthesis in the cotyledons, idk if cannabis is one. Cotyledons can hang on for weeks. Alternating nodes is just a sign of sexual maturity. This is basic Botany, cannabis isn't special.

Cannabis cotyledoms do photosynthesise.

As soon as it sprouts it is in veg stage, which, to me, has two stages - before it shows sex (juvenile) and after it shows sex (adult).

If all is well the plant generally shows sex about 35 to 40 days after the seed pops in germ.

But... i have a pair of plants that i over watered a bit and the are a bit stunted. They are 32 days old and it will be a good while yet, maybe two weeks, before i will be able to see pistils or otherwise. (Fems tend to show pistils first...balls take a little longer)

That would explain why they can stay around for so long.

Some people think they are food stores but i think they are getting confused with the endosperm. Really they are just basic leaves that photosynthesise and exchange gasses and hence more of a food producer not food store.

A simple structure that starts everything of. Until the true leaves form the seedling is reliant on its cotyledons to photosynthesise and produce energy. Thinking they are food stores and letting them yellow is the biggest crock of crap ive ever heard.

Well I'll be you are correct. I wasn't aware of this and it will change my grown plan just a little.

"In the case of dicot seedlings whose cotyledons are photosynthetic, the cotyledons are functionally similar to leaves. However, true leaves and cotyledons are developmentally distinct. Cotyledons are formed during embryogenesis, along with the root and shoot meristems, and are therefore present in the seed prior to germination. True leaves, however, are formed post-embryonically (i.e. after germination) from the shoot apical meristem, which is responsible for generating subsequent aerial portions of the plant.

The cotyledon of grasses and many other monocotyledons is a highly modified leaf composed of a scutellum and a coleoptile. The scutellum is a tissue within the seed that is specialized to absorb stored food from the adjacent endosperm. The coleoptile is a protective cap that covers the plumule (precursor to the stem and leaves of the plant)."
