Royal Gold Crown Jewels Bloom 1-4-2 Organic Bloom Fertilizer

Developed with Certified Soil Scientists and Crop Consultants in Humboldt County, Royal Gold Crown Jewels Bloom 1-4-2 is a one-part, OMRI-Listed formula designed to power the bloom phase with clean, consistent results. Its micronized ingredients deliver a steady, balanced release—ideal for adjusting soil before blossom set or as a top-dress throughout fruiting and flowering. The blend includes seabird guano, rock phosphate, gypsum, alfalfa, basalt, kelp meal, neem seed meal, shrimp meal, Epsom salt, sulfate of potash, and dolomite, providing N-P-K (1-4-2) plus calcium (11%) and magnesium (0.5%) for robust structure and metabolism.
