Add potash at 1-2mL during the flower cycle. PK Booster is PH balanced and chelated for maximum uptake. 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
