Mills Nutrients 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 build up.

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.
