Cutting Edge pH Down Cutting Edge's pH Down concentrated adjustment liquid, acidic buffer lowers water and nutrient solution pH. Highly concentrated, use conservatively. Slowly add to pure water or nutrient solution, at small intervals. Note beginning reading and then test pH. Repeat small application process and stir well, until desired pH is achieved. Amount of CES pH Down required for adjustment will vary, depending on the strength of nutrient mixture and purity of the water source used. May be diluted when applied to reservoir with nutrients. Developed with Cutting Edge Solutions nutrients Highly concentrated for rapid adjustment Designed for use with plants No artificial dyes 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. Commonly recommended pH range for hydroponics and soil is 5.5 to 6.5 Use calibrated digital pH testing instrument, or use pH indicator strips to confirm the ideal pH of your water and nutrient solution.
