Tip Don't use too much pH+ and pH-

Using too much pH+ & pH- with each other disturbs the bicarbonate concentration and the water’s buffering capacity. Also, the mutual balance between the different nutrient elements will be influenced and deficiencies could arise. Adding too much pH- or pH+ can be prevented by first diluting it with water before adding it to the solution.
