Mills Ultimate PK

Mills Nutrients Ultimate PK | Professional PK Booster for Maximum Yields

Mills Nutrients Ultimate PK is a high-performance phosphorus and potassium booster engineered to maximise fruit size, quality, and yield in the final weeks of the bloom cycle. Delivering a potent 0-7-6 PK ratio using ultra-clean, highly soluble mineral salts, Ultimate PK gives flowering plants exactly what they demand at the most critical stage of their development.

How Mills Ultimate PK Works

As plants enter peak flower, their requirement for phosphorus and potassium rises sharply. Ultimate PK meets this increased demand with precision, using clean, super-soluble mineral salts that are rapidly absorbed and leave minimal residue — making it an excellent choice for soil, coco coir, and hydroponic systems alike, with virtually no risk of blockages or salt buildup.

The high bioavailability of these minerals ensures maximum uptake efficiency at exactly the right time, driving exceptional fruit development, enhanced essential oil production, and the kind of flavour and aroma profiles that set premium harvests apart.

Recommended Feeding Schedule

For best results, follow the Mills two-stage PK programme:

From week 6, C4 and Ultimate PK are used together for a powerful overlapping boost before transitioning to Ultimate PK alone through to harvest. Always refer to the Mills Nutrients feed chart in the downloads section for the complete schedule.

How to Use Mills Ultimate PK

Apply Ultimate PK at a rate of 2 ml po litri during the last 2–4 weeks of the flowering stage. Always add one nutrient or additive at a time, stirring thoroughly between each addition.

Store at room temperature and keep away from freezing conditions, as exposure to frost will compromise the product's effectiveness.
