Devil Harvests PK Booster

Devil Harvests PK Booster is PH balanced and chelated for maximum uptake.

Add potash at 1-2mL during the flower cycle.

Potash should be added to the tank after water and silica but before any other additives for the best results.

Note: PK Booster can be added in higher doses from week 5 onwards to harden flowers and increase yields. Adjust final PH to 5.5-6.3.

All Devil Harvests products have been scientifically formulated using the highest quality and purest of raw materials possible.
