Including the 8 days already done and when should I start adding my plant magic old timer grow 5-3-3 ? Thanks in advance

Leafs standing up is fine.
Don't start feeding until day 21 or so, depending what soil you are in.
Veg as long as you have room for.

I'd say veg for at least 6 weeks, or longer of you have space. The longer in veg the bigger your yields, so use up all of the space you're working with. And yeah leaves standing up are fine, they just want to make the most of the light.

Plagron light mix 1/4 nutes sound okay from 3 weeks old or ?

No reply still ?
