Keep your pH monitored on a daily basis. As plants grow and becomelarger, the demand for nutrients increases.
This means the nutrient levels(conductivity) and pH in the solution can fluctuate and therefore should betested and adjusted if necessary to maintain an
optimum working nutrient solution.
Nutrient requirements vary from plant to plant; therefore the idealpH varies from plant to plant also.
The pH is usually adjusted by addingan acid to lower the pH (HY-GEN pH DOWN) or alkali to increase the pH(HY-GEN pH UP).
Remember to regularly calibrate your pH meter with Quality Scientific Grade HY-GEN pH Buffer 4 and HY-GEN pH Buffer7 Calibration Solutions.
