Athena Blended PK is a low‑nitrogen liquid booster formulated for the mid‑ to late‑flowering stage of plants. With an N‑P‑K ratio of approximately 0‑4‑5, it provides additional phosphorus and potassium that high‑yielding plants require for maximum production. Many PK boosters add excessive amounts of these elements and inadvertently reduce availability of calcium and magnesium—Athena’s formula is designed for balanced elemental bio‑availability during flower development.
