Tip Mixing nutrients

Measuring the nutrient reservoir works as follows: Take EC/ppm as the starting point, measure it and determine whether it should be higher or lower, based on the values shown in the instructions. Only then should you adjust the pH if necessary. Try to get the nutrient solution’s pH value correct at the first attempt.
