Athena Blended PK is a zero-nitrogen liquid phosphorus and potassium bloom supplement designed to be layered over the Athena Blended Bloom A+B base during the mid-to-late flowering phase, from week 3 through late bloom. Its 0-4-5 mineral formulation provides additional P and K during peak flowering demand without adding nitrogen, while remaining compatible with standard dosing and irrigation systems.

Key Advantage: Athena Blended PK provides a targeted P and K boost without adding nitrogen, allowing growers to increase flowering-phase phosphorus and potassium while keeping Bloom A+B as the base feed. Its relatively moderate 0-4-5 profile is designed to provide additional PK while helping maintain Ca/Mg availability, and the liquid formulation integrates easily into automated fertigation systems.
