Key Benefits of using Mills Ultimate PK
- Larger Flowers: Ultimate PK is a potent bloom stimulant containing potassium and phosphite, designed to be used in the final weeks of flower development.
- Denser Heavier Fruit Sets: It works quickly to enhance the production of essential oils, acting as a strengthener and enhancer to improve the taste and smell of your plants.
- Contains Phosphites: Ultimate PK is a powerful bloom stimulant with a high level of Phosphite, crucial for the later stages of flowering.
- Bioavailable form of Phosphate: Its highly bioavailable form of phosphate promotes healthier root systems and better nutrient absorption, leading to optimal plant health during the later bloom cycle.

How to use Mills Ultimate PK

Frequently Asked Questions
Is Mills Ultimate PK just like all other PK's?
No, Mills Ultimate PK is not like all other PK supplements. It combines phosphorus and potassium with additional micronutrients and bio-stimulants to enhance flower development, density, and overall yield. Its unique formulation supports late-stage plant growth by boosting energy transfer, nutrient transport, and essential oil production. This makes it more advanced than standard PK boosters.
Isn't Ultimate PK just like Mills C4?
Mills Ultimate PK and Mills C4 are similar in supporting flowering but serve different purposes:
- Mills C4: A bloom booster with a complex blend of carbohydrates, amino acids, and trace minerals. It promotes early and mid-flower development, boosting flower size, terpene production, and overall plant vigour.
- Mills Ultimate PK: A late-stage bloom enhancer focused on increasing flower density, essential oil production, and final yield. It delivers high concentrations of phosphorus and potassium with added micronutrients for maximum flower development.
Using both products together can optimise results throughout the entire flowering phase.
