Shogun Fertilisers PK Warrior 9/18 delivers the right amount of phosphorous and potassium to your plants at exactly the right time, giving increased fruit and flower production for the best quality and yields.

PK Warrior 9/18 provides a highly concentrated solution, giving better value than other leading PK brands out there. It has been designed for maximum plant growth and availability, and this is evident in the results!

Why 9/18? Well, most nutrient solutions will already be carrying relatively high phosphate levels, and oversupply of this element can be detrimental to plant quality. Potassium drives the sugar production in your plants, and this element is what they need more of. The 9/18 gives the optimum level of both elements and means you can use it for longer without any negative effects.

The formula includes plant sterols alongside other natural ingredients, maximising nutrient uptake and utilisation, and is manufactured using high grade agro-chemicals and specific organic acids. This allows more targeted nutrition within your plants, giving bigger yields. What’s more, Shogun Fertilisers PK Warrior is suitable for all types of growing system.


  • Optimum Phosphorus and Potassium ratio for maximum flower potential
  • Includes Plant Sterols and other natural ingredients to maximise nutrient uptake and utilisation
  • Targeted nutrition for the reproductive phase of crops
  • Manufactured using high grade agro-chemicals and specific organic acids
  • Suitable for use in all growing systems


PK Warrior is highly concentrated and should be diluted at just 1ml/L for the first week of use and then 0.5ml/L from that point onwards. Use from the fourth week of the flowering cycle or when flowers and fruits begin to appear.
