Honestly it looks really like mostly clay. I'd add some peat moss and pumice. But that soil is probably pretty rich, so it looks like a good starting point actually. I'm just being a smartass. Can't help it. I was born like this,I can't math so I'll assume it's a ten thanks heaps bro
?Soil health is measured in fatty acid content. The only thing separating hydro from soil. You'd think pot growers would choose microbes and inputs that created the best fatty acid profile, since lipoxygenase products literally define the crops value.
