Mills Nutrients Ultimate PK 5L – Powerful Bloom Booster for Dense, Heavy Flowers

Unlock maximum flower density and weight with Mills Nutrients Ultimate PK 5L, a premium bloom booster specifically formulated to enhance flavor, aroma, essential oils, and final yield during the last weeks of flowering. Ultimate PK combines high-powered phosphorus and potassium (PK) with plant-available micronutrients to support explosive bloom development and stronger plant structure.

This powerful formula helps plants harden up buds, increase essential oil content, and improve overall quality during the critical late flowering phase. Ultimate PK also improves nutrient uptake and strengthens cell walls, resulting in tighter flowers and increased harvest weight.

Designed for use in soil, coco, and hydroponic systems, Ultimate PK integrates seamlessly into the Mills feeding schedule and complements the Mills Basis A/B, C4, and other bloom-phase nutrients.
