Powder C is a bloom-stage fertilizer built on a 0-32-32 formula: no nitrogen, heavy on phosphorus and potassium. It also carries magnesium and sulfur, which support chlorophyll and nutrient uptake. It is fully water-soluble and mixes clean, so it works in hydroponics, coco, soil and recirculating systems, and it slots into multi-part programs as the bloom component. It suits growers running a two- or three-part feed schedule who want to push flowering and fruiting without extra nitrogen; compared with all-in-one bloom boosters it asks more of the user, since it is one part of a program rather than a standalone feed.
