Mills Ultimate PK

Ultimate PK, as the name suggests is a powerful potassium and phosphorus based blooming additive! Use during the final stages of flowering to help bulk up your yield, harden your flowers and deliver results you did not think possible. It will also promote a strong, healthy root system with maximum nutrient uptake even during this final phase of the bloom cycle.

How It Works

Potassium and phosphorus are well known as being the main elements that contribute to strong growth during flowering. As the plant progresses through the bloom phase, the need for these elements become greater and in order to get the best yields correct supplementation is needed. Ultimate PK does just this! By using a highly bioavailable form of phosphorus (phosphite), the root system of your plant is stimulated to ensure optimum nutrient uptake, this in turn allows it to utilise the nutrition within Ultimate PK and any other additives you are using to maximum effect. Ultimate PK contains phosphorus and potassium derived from the highest quality sources and will provide your plant these important elements in this crucial final few weeks of growth. Expect to see greater yields with extra firm fruits and flowers of the highest quality.

How To Use Mills Ultimate PK

Use Ultimate PK during the final 2-4 weeks of flowering. The Mills nutrient chart recommends a dose of 2-2.5ml per litre of water. Ultimate PK can be used in soil, coco or hydroponic applications.
