    Hello –

    I am trying to reduce the ph of 5 gallons of nutrient solution from 7 to 6.5. How much ph down should I start with? Is there an amount per gallon of the ph down that gives you a starting point to reduce the pH?

    Hi Jim —

    The best way to go about using a product to reduce pH, such as our General Hydroponics pH Down, is to simply start adding a little at a time to your nutrient solution and testing after each addition. There is no set amount to add due to the fact that the purity of the water and the nutrient strengths vary from application to application.

    Here is a link to the product: https://www.planetnatural.com/product/general-hydroponics-ph-down/.

    Good luck and happy growing!
