Nutrifield PK Heavy 1L Old Formula

PK Heavy is a refined synthetic phosphorous (P) and potassium (K) supplement to support the plant’s increased PK needs during the flowering phase. Phosphorous is a key building block of the plant’s energy molecule, ATP (adenosine tri-phosphate), which is required to support the elevated levels of metabolic activities during flowering, such as photosynthesis and respiration. It also contains Zinc (Zn) which aids protein metabolism, helps maintain cell membrane integrity, and assists chlorophyll production. PK Heavy™ is made up of highly concentrated minerals that promote massive flower development which you can clearly see in size and weight after application. PK Heavy™ is compatible with all growing methods and mediums.

Potassium is involved in the movement of water and nutrients within the plant, and supports the increased requirements of the development of healthy flowering buds. The increased supply of phosphorous and potassium during flowering, supports the formation of additional flowering sites and promotes enhanced flower yield and quality.
