Water After Adding Nutrients
Adding nutrients to your water will increase the ph so you must test how much it has increased by. If it is not fixed your plant will not easily absorb the nutrients it needs to thrive and could even experience nutrient lockout. To prevent this we use are PH Tester and PH down, adding drops and testing the solution until we are back at our desired levels.
Pot Run Off Water
Measuring the ph level of your run off will give you the exact ph level of the water your plant uses after it has absorbed everything available in the soil.
