Athena PK

Athena PK is a clean, no-nitrogen bloom booster designed for mid-to-late flowering.

Adds extra phosphorus and potassium to support heavy production while maintaining balanced nutrient availability.

NPK: 0-4-5.

Zero nitrogen formula prevents disrupting calcium and magnesium availability.

Feeding Rate: Add 4-15 mL per gallon of water during the flowering phase, starting in week 3 of flower.

Many PK boosters add far too much of these elements and create problems — Athena PK is carefully balanced to boost essential oil and terpene production without causing nutrient lockout.

EC Targets with PK: Maintain overall EC in the 2.2-2.8 range during peak flower when adding PK to Bloom A+B.

Part of the Athena Blended Line.

Compatible with both Blended and Pro Line feeding programs.
