Inizio Stato vegetativo o ancora è Germoglio dà ...

ciao fratello, di norma andrebbe considerato l'inizio della vegetativa quando ha fatto venire fuori la prima foglia dulta a più di 3 punte. Valuta tu :) Buona fortuna e buon viaggio con lei!!

Hey there I would still treat the seedling as a seedling. I don’t say a plant is in veg until it’s 6 to 8inchs tall and starts to get sturdy

As soon as the first true leaves open up, it is a functioning plant in the veg stage.........IMO.

A cannabis plant is considered to enter its vegetative or “generative” stage from the appearance of the first pair of true leaves. Therefore, you can start gradually increasing your EC level and adding some growth fertilizer.

This is an arbitrary distinction... I don't think it is considered beyond a seedling until it has 5-6 nodes, but this label is irrelevant. You simply give it what it demands. If it needs full power light (35-40 dli) and needs proper fertillization, then that is all that matters, regarldess of the exact category it currently fits into. It correlates, but it is not 1:1. vegetative growth = new leaf growth and stem elongation. Even in "bloom phase" vege growth continues before it tails off. These particular categories are mean to be conceptual only. Simple observe and react to the plant and you'll do fine. If soilless, definitely starat fertigating with 10% runoff each time... if soil, you wait until you need to supplement what is exhaused from the soil. if familiar, you can have a schedule that pre-empts any deficiencies, if not familiar... i'd take good notes and react to hints of deficiencies your first cycle... once the fertilization ramp-up is mapped out you can avoid them next time. *change soils or fertilizer products and you may need to re-learn that process in future. Allow new growth node spacing to dictate your light intensity... Easy-peasy.. take the choices out of the equation. simply observe and react.

In my opinion it's first day of growing stage. Good luck

Vegging consist of germination to sprout to adolescence of the plant. Then flower kicks in. I'd say its still a sprout as its not put on many adult leaves or nodes.
