Emerald Harvest Cali Pro Bloom A&B 9.46L

Cali Pro Bloom A&B is the flowering-stage formulation in Emerald Harvest's two-part base nutrient system, picking up where Cali Pro Grow leaves off. As the plant transitions from vegetative growth into the reproductive phase, its nutritional requirements shift: nitrogen demand moderates while phosphorus and potassium requirements increase substantially to support flower formation, fruit development, and carbohydrate transport. Cali Pro Bloom is formulated around these priorities.

The A part leads with potassium nitrate and calcium nitrate to maintain calcium availability and support structural development in developing flowers, with the full chelated micronutrient suite carried through from the vegetative phase. The B part supplies elevated phosphorus and potassium via monopotassium phosphate and potassium nitrate, alongside magnesium sulphate to support photosynthesis and nutrient translocation through the flowering period. Mix equal volumes of A and B at the recommended application rate. Shelf life of three years or more. Use in conjunction with Cali Pro Grow A&B and the Emerald Harvest additive range.
