Ultimate PK

Ultimate PK by Mills Nutrients is a bulking booster designed to maximise bud production and quality during the critical final flowering stage. Its advanced bio-mineral formula of the highest quality combines phosphorus and potassium in optimal proportions, alongside a selection of essential micronutrients, to increase bulking processes.

Features of Mills Ultimate PK:

Mills Ultimate PK acts as a stimulator of bulking and maturation processes, also promoting robust cellular structure that allows plants to support more weight.

The PK and other elements in Ultimate PK help increase the production of terpenes and active compounds resulting in more aromatic and potent flowers.

Compatible with all substrate types, including soil, coco and hydroponics, and can be applied both by watering and foliar spray. 

Mills Ultimate PK usage recommendations:

Apply during the last 2 to 4 weeks of the flowering stage at 2 to 2.5ml per litre of water when watering.

It is recommended to use it combined with other products from the Mills range, such as Mills C4 and Mills Basis A.
