Top Tip
For best results, pair Shogun PK Warrior 9/18 with a flowering booster like Shogun Sumo Boost or Sumo Active Boost. This helps maximise nutrient uptake and supports stronger flower development throughout the bloom stage.
By 25 to 50% reduction, you mean for example if the ec shows 1.8, reduce to 1.2?
When making up your solution, it's best to add your additives & boosters first, then top up to target strength with your base nutirent. You will typically find that you need to use less of your base nutrient when using PK Warrior, you will not need to lower the amount of Sumo Boost used.
