Monkey Nutrients PK 14/15 Is a Phosphorus and Potassium supplement. It is designed to stimulate flower production and produce high levels of yield and flavour enhancing PK, when the plant needs it most. A PK boost early in bloom triggers the onset of fruit production, directing photosynthetic energy to shoots tips, creating flowering sites. During the crucial mid-flower point, allowing your plant access to optimum levels of PK can make or break harvest results. Through extensive research and testing we found the ratio PK14/15 is the perfect concentration required for plants to reach their full harvest potential. What is Monkey Nutrients PK 14/15? • A complimentary flowering supplement. Our Phosphorus and Potassium (PK) boost elevates PK levels increasing and enhancing floral development. • PK 14/15 refers to its ratio and balance. During early to mid flower a ratio of 14% Phosphorus and 15% potassium will significantly improve yields. • Phosphorus (P) an essential macro nutrient for plant life. P is not only structurally important for plant cells, it aids in energy production and transfer. • Potassium (K) an essential macro nutrient for plant life. K is a catalyst for carbohydrate metabolism as well another regulatory functions. The bio-stimulants in the nutrient range also have a high demand for K.
