Terra Buena is a good Colorado local soil mixed by knowledgeable growers. They deliver all over the seast of co by the truck load. 10 yards is cheap like 20$ a yard.
Amend with azomite,
composted chicken manure ( cheap)., 30$ a yard it's everywhere
Bone meal, yes it's ok
Kelp meal for k,
Myco under root ball
In veg top dress every couple weeks with more chicken manure
Also tea with a worm cast, humisoil, local compost, molasses, concoction every few weeks. I only tea with these bc of the cost of worm cast and humisoil. Goes a long way with tea and not amending with them. Maybe pre inoculate a fungal tea once or twice if yer feeling frisky, you can use that as a good foiler also. Bountea has a good one, fungals are different though, no molasses to feed the tea only kelp or rock phosphate and bubble for two days.
Top dress with more kelp meal, azomite, and bone leading into , and another time in bud. Also more chicken up to 4 th week in bud, boom boom boom. And tea tea tea.
Get some good vigorous genetics. I ran Devine last year with somewhat this method in 200 gal smarties.
