I honestly don't know what's going on with these ones it's looking like I'm out of the money that I put up for femini seeds and I might have to start over. Sigh I haven't had any so far that didn't take. I usually don't have problems until later.
If it’s from seed, I count veg from the first true leaves. If it’s a clone, I count veg once it’s established and growing again.
I’ve also read that the first 2 weeks after germination are considered seedling stage, then veg count starts.
