Cronk Bloom 0-5-3 | Flowering Stage Plant Fertilizer
Bloom 0-5-3 is a nitrogen-free flowering fertilizer that delivers elevated phosphorus and potassium for flower initiation, dense bud development, and enhanced resin production. The zero-nitrogen formula prevents vegetative interference during bloom, allowing plants to focus energy entirely on reproductive growth.
Excess nitrogen during flowering promotes unwanted leaf growth, delays maturation, and reduces flower quality. Bloom eliminates this problem while supplying the phosphorus for ATP energy production and potassium for terpene synthesis, sugar transport, and stem strength under heavy flower loads.
Key Benefits
- Zero nitrogen prevents leafy growth that diverts resources from flowers
- Elevated phosphorus (5%) drives flower initiation and energy-intensive bloom development
- Potassium (3%) enhances flower density, resin production, and aromatic compound synthesis
- Fully soluble for soil, coco coir, and hydroponic applications
Ideal For
Growers transitioning plants from vegetative growth to flowering. Gradually increase Bloom while decreasing Grow as plants enter and progress through bloom for optimized stage-specific nutrition.
