Athena PK 4liter neat mat 4 set to a built-inAthena PK is a balanced bloom boosting complement to our Bloom fertilizers. This clean liquid booster is designed to supplement during the mid to late flowering phase. Athena PK is a low Nitrogen booster that provides additional Phosphorus and Potassium that high yielding plants require for maximal production. Many PK boosters add far too much of these elements and create a cascade of problems, such as reducing Calcium and Magnesium availability.
