I agree mate, as an organic farmer, I tend to rely on nutrients from all pools, not just the water soluble pools. The system we have uses a building N and K system with added Moly. Once we get this base, we start to load up added liquid P, Ca, Mg, S etc. We do have NPK, but we rely less on this than other systems, even other organic ones.
We look at the modulating effects of bacterial interactions in the rhizosphere and beyond and seek to encourage the positive outcomes by stimulating the right biology and volatiles, which in turn help our plants manage growth, stress and life.
We also have a range of Nano products that assist CO2 applications without the typical stress. We work with science and I only set this up because I was sick of the myths among other nutrient vendors. Happy to answer any questions if you ever have any bro. I don't know everything, but we can learn together for sure
