The need for a PK type product during the flowering period is obvious. You are trying to alter the NPK ratio of your nutrient solution to maximise its efficiency for fruit and flower production.

SHOGUN have carried out extensive field trials and scientific studies to work out the ratios of phosphorus and potassium to include in PK Warrior. In general, most nutrient manufacturers have a 13/14 formulation – trial data indicates that this is far from optimum. Most nutrient solutions, specifically bloom formulations are already carrying relatively high phosphate levels and despite this being an important flowering element you need to avoid oversupply as your plant will struggle to use and store the excess, resulting in fruit quality decreases.

Potassium on the other hand is the element that drives sugar production in your fruits and it is this element that your plants need in a higher proportion from your PK additive. After large scale testing using a multitude of PK ratio products, SHOGUN have found that the 9/18 ratio offers the optimum level of potassium uptake without overloading on phosphorus in the process. This also allows PK Warrior to be used for longer during the flowering period without negative effect, feeding the need for yield enhancing potassium for as long as possible.


Add at a rate of 0.5 – 1ml per litre to your nutrient reservoir or watering can.

Use from the fourth week of the flowering cycle (or when flowers and fruits begin to form) and for a period of four weeks. Using in conjunction with Sumo Active Boost will maximise your plants demand for PK Warrior 9/18.
