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 maximum 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 4-15 ml of Athena PK per gallon of water during the flowering phase, starting in week 3.
See Feed Schedules for specific application recommendations.
