How to react to m-fungi

Sea salt is overwhelmingly sodium chloride. Cannabis is sensitive to high salinity. High sodium levels disrupt osmotic pressure, meaning the plant can no longer draw water up through its roots, effectively causing it to die of thirst even in wet soil. Salt is a desiccant and a preservative—it kills microbiology. Dropping salt into the substrate will dehydrate and destroy the delicate hyphal threads of the very mycorrhizal fungi this person is trying to "unlock." Excess sodium aggressively competes with calcium and potassium for uptake at the root zone, leading to rapid, severe deficiencies. In a water-only system, the entire nutrient delivery engine is powered by a healthy, thriving microbial food web breaking down organic matter. Introducing raw salt into that environment is the equivalent of dropping a bomb on the ecosystem doing all the heavy lifting. Do not do this... Bro science at its finest.... Are you coming at this from about Korean Natural Farming (KNF), which sometimes uses highly diluted seawater (at ratios like 1:1000) for trace minerals?? You have misinterpreted this into dropping raw sea salt directly onto the substrate.

Why is your plant so yellow?
