The 13/14 ratio drives flower formation from week one of bloom, leading to heavier, more aromatic tops at harvest.
Phosphorus supports a denser root mass that absorbs water and nutrients more efficiently throughout the cycle.
Highly assimilable liquid form. Mixes seamlessly into your watering tank in soil, coco or hydroponic setups.
Week 1: 0.25 mL/L. Week 2: 0.75 mL/L. Week 3: 1 mL/L. Following weeks: 1 to 1.5 mL/L. Stop BN P-K on the final week and flush with Bio Nova Vitasol for a clean finish.
Does BN P-K 13/14 replace my base nutrient?No. It is a booster you add to your usual bloom feed. It reinforces P and K supply without replacing nitrogen, micronutrients or root stimulators.
One 250 mL bottle covers several bloom cycles on a small indoor grow — a strong value-for-money entry into the Bio Nova line.
