How often should I check my pH level?

As pH is a crucial factor in plant nutrition, it is recommended that you check your pH level every day. There are several factors that may alter the pH level. For example, if your plants are in full growth mode and are consuming a lot of food, the pH will fluctuate greatly, even if you have a stabilised nutrient to begin with. However, you do not have to readjust the pH all the time; you can allow the pH to fluctuate between 5.5 and 6.5.
