Athena 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. Balanced elemental bioavailability is essential in the flowering phase to boost essential oil and terpene production.
