PK Heavy® is a precision-engineered phosphorus and potassium additive formulated to support early and mid-flowering demands. Unlike standard PK products that rely on a single nutrient source, PK Heavy® uses multiple premium mineral inputs to improve bioavailability and uptake efficiency as plant requirements change through bloom.

This formulation supports strong flower initiation, tight stacking, and increased flower weight without causing nutrient antagonism or lockout. When used alongside Nutrifield base nutrients and Crystalic®, PK Heavy® delivers consistent, balanced support during the most demanding stages of flowering.

Suitable for hydro, coco, and soil systems, PK Heavy® is designed for growers chasing performance without compromising system stability.
