Athena PK — 940ml

Athena PK — 940ml

Athena PK is a concentrated phosphorus-potassium supplement for peak flowering — designed to pair with Athena Bloom A&B during the critical mid-flower window when bud development is most intense. Athena's PK formulation is calibrated to complement their base nutrients without causing the lockout issues that overloading P and K can trigger.

Why growers choose Athena PK:

• Calibrated to complement Athena Bloom — avoids P/K overload
• Peak-flower application — 2-3 week mid-bloom window
• Concentrated formula — small doses, significant effect
• Available 940ml, 3.78L, and 18.92L

Who it's not for:

Athena PK is a short-duration booster, not a full-cycle product. If already running a PK booster from another brand, don't stack. Monitor EC when adding. For comparison: similar role to Canna PK 13/14, Bio Nova PK 13/14.
