Hammerhead by AN is a well-known PK boost, and this formulation comes pretty close, and uses only 3 ingredients (well actually 4 if you count water). You can make your own for a fraction of the cost of commercial PK boosting products.
RECIPE:
- Potassium sulfate aka soluble potash = 65 grams
- Monopotassium Phosphate aka MKP= 100 grams
- Magnesium Sulphate aka epsom salt = 4 grams
- 1 quart of water
Add the soluble potash to your water first and let that dissolve, and then the epsom salts, and then add the MKP.
USAGE:
NOTE: always add first to your water, before adding the nutrients
Starting at 10 days into flowering add 1 ml per liter of water
