Mostly Bat poop and fish/sea based NPK, some vitamin additives like Super thrive or something similar, and mycorrhizae. Even that Alaska fish emulsion stuff at the big hardware stores works great. Look into cooking your own soil and soil recipes to save cash.
I’m still a rookie when it comes to organic growing, most of my experience is synthetic hydro followed by indoor soil. If you’re really interested, search for journals from Conradino23 and/or Doc Bud. They each have their own style but grow amazing looking organic flower. Off the charts good. I look at their journals when I want to learn organic soil techniques/hows/whys and relationships in between.
