Description 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. Application Rates: Add 3-10 mL per gallon of water during the flowering phase starting in week 3. See Feed Schedules for specific application recommendations. Best Practices Shake well before use. Use clean measuring instruments--do not put anything into the bottle. Monitor EC regularly and adjust accordingly based on the crop and growth stage. Adjust pH to proper levels after mixing all fertilizers and additives. Store closed in original packaging at a temperature between 45° F and 85° F.
