Mills Ultimate PK — Final 2-4 Weeks Flowering Additive

Mills Ultimate PK — Essential Final-Weeks Flowering Additive

An essential flowering additive suitable for the last 2-4 weeks of the blooming stage — top-quality Mills ingredients offer plants the nutritional support needed for a grand finale harvest. The product strengthens the plant's internal structure (supporting heavy flowers physically) while driving high-yield results. Mills has spent years perfecting this late-flower PK formulation, and it shows in the results.

Why growers choose Mills Ultimate PK:

• Last 2-4 weeks of flowering focus — precisely targeted at the grand finale window
• Strengthens plant internal structure — heavy flowers need physical support; Ultimate PK helps
• High-yield harvest support — measurable final-weight gains when applied correctly
• Top-quality Mills ingredients — premium formulation quality
• Years of refinement — not a new unproven formulation, properly developed
• Pairs with Mills feeding programme — Basis A&B, Start-R, Vitalize integrate cleanly
• Works with any base nutrient — universal late-flower compatibility

Who it's not for:

Specifically for the LAST 2-4 WEEKS of flowering — not a mid-flower or early-flower product. For mid-flower boosting, use Shogun PK Warrior, Monkey PK 9/18, or Buddha's Tree PK 9-18. An additive, not a base nutrient. Stop 7-10 days before harvest for a proper flush. Follow label dilution; high-PK over-application locks out calcium.
