Monkey PK 9/18 — Concentrated Mid-Flower Phosphorus & Potassium Booster

Monkey Magic's PK 9/18 — the final flowering piece of the Monkey Nutrients puzzle. A concentrated 9/18 ratio of phosphorus and potassium, the exact balance plants need for peak mid-flower performance. Access to high P and K during the critical mid-flowering window can make or break harvest results; Monkey PK 9/18 delivers exactly what's needed at exactly the right time.

Why growers choose Monkey PK 9/18:

  • Classic 9/18 PK ratio — industry-standard proportions for mid-flower boosting
  • Concentrated formulation — small doses, good value per grow
  • Drives yield density and quality — not just more weight, better structure
  • Critical mid-flower window coverage — the weeks where PK boosting delivers most
  • Pairs with Monkey Magic range — integrates with the wider Monkey feeding programme
  • Works alongside any base nutrient — not Monkey-only, universal PK booster
  • Professional-grade formulation — matches premium brands at competitive pricing

Who it's not for:

An additive, not a base nutrient — use alongside a full feeding programme. For similar 9/18 PK boosting at different price points: Buddha's Tree PK 9-18, Shogun PK Warrior 9/18, or Athena PK are alternatives. Discontinue 7-10 days before harvest. Follow label dilution; over-applied PK can lock out calcium causing deficiencies. Mid-flower focus — for early flower transition, use different additives (Bud Ignitor, Flower Burst).
