PK boosters are essential when trying to maximise your yield. Phosphorus and Potassium PK are required in higher levels during the later stages of flower to develop larger denser fruits.

Ultimate PK by Mills Nutrients has been developed over time not only to increase yield but also increase root health and natural sugar production to enhance flavour and overall plant health.

Mills PK contains high levels of Phosphite which when combined with the trace minerals help to develop root growth and overall plant vigour.
