How should a grower mix nutrients?
It is important that a grower should mix their nutrients separately, e.g. first apply part A into the reservoir and mix, and then apply required amounts of part B to the reservoir and mix. A two or three part nutrient solution should never be added together before being added to the reservoir (see “Why are some nutrients split into A and B formulas”). At this point a ppm and a pH reading should be taken. If the grower is adding enhancers then the enhancers should be added to the reservoir separately. A ppm and pH reading should be taken after each enhancer addition to the reservoir. Once the grower has added all the required nutrients and enhancers then the pH of the nutrient solution must be adjusted to 5.8 to 6.2, 6 being ideal.
