Instructions:
Highly concentrated, use conservatively. Slowly add to water and nutrient solution, at small intervals. Note beginning reading and then test pH. Repeat small application process and stir well, until desired pH is achieved. Note amount used per gallon in reservoir, for future application estimates.

Amount of pH DOWN required for adjustment will vary, depending on the strength of nutrient mixture and purity of the water source used.

This acidic liquid lowers pH.
