First, measure the PH of the prepared nutrient solution. If needed, add the specified adjuster gradually into the nutrient solution. Mix carefully and check the change in the pH level. Continue by adding needed amounts of the adjuster until reaching the desired PH level. Make certain you stir the nutrient solution carefully after each adding, and before measuring.
• To increase the PH during growth period use the PH+ adjuster
• To decrease the PH during growth period use the PH- adjuster
• To increase the PH during bloom period use the PH+ bloom adjuster
• To decrease the PH during bloom period use the PH- bloom adjuster
