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. How to use Shake well before use. Use clean measuring instruments, do not put anything into the bottle. Always use equal parts of Athena Bloom A & B to maintain proper mineral ratios. Monitor EC regularly and adjust accordingly based on crop and growth stage. Adjust pH to proper levels after mixing all fertilizers and additives. Do not combine in undiluted form. Store closed in original packaging at a temperature between 8° C and 30° C.
