Magnesium, sulfur, phosphorus and potassium driver for structure and bulk.
Part B carries the magnesium, sulfur, phosphorus and potassium load of the program. At 2-13-17 with a precision-tuned P-to-K ratio, it supports prolific vegetative growth and the production of essential plant compounds, working in tandem with Part A to deliver complete base nutrition.
Add Part B to the reservoir after Part A is fully dissolved, agitating 3–5 minutes. If running PhosZyme, add it together with Part B. Dose by target EC per growth stage and validate EC and pH before feeding. Fully soluble with no sediment — injector- and emitter-safe.
