Yep, about 3 or 4 weeks mate, then feed.
Vitamins and tonic can be introduced a little earlier if you want, i use Superthrive for instance, good for all seedling and veg growth, but not NPK, enough in the soil and they need to find their feet/roots.
Welcome mate, good luck with your grow.
Always ask questions and read growguides etc, assume nothing at first, Cannabis is quite the idiosyncratic genus.
