gah those dudes are funny. Its like fishing or golf nowadays.
Organics is a massive subject, far more detailed and complex than a super soil intimates. If we take global soil profile studies, there is none anywhere that lacks the elemental values needed to grow a plant. Given a single grain of sand likely contains enough N to feed an acre of maize for a year, its more about learning how to access the tools from those things around you.
Buying a super soil made up of 50 components shipped from all over the world, kind of defeats the subject before you begin. Now I know my organics sequesters more carbon than a mineral rockwool grow, but it might not make me a zero if I have 1000's of miles on my soil before I plant.
I use a simple coco and home sourced peat mix, no perlite, no amendments, just me my plant and several billion bacterial workers a heap of friendly fungus and mold, and a bunch of resonance in a balanced environment with a tweak of thermodynamic nano magic.
