PRECAUTIONS: Note above the “A” and “B” formulas…
There is a reason…
Usually, the calcium containing compounds are kept separate from the phosphate and sulfate compounds. Why? In high concentration the calcium will combine with the phosphates and sulfates to form insoluble precipitates.

THEREFORE:
A typical nutrient solution will be divided into 3 tanks:
Calcium/iron tank (iron gives it a reddish color)
Macro/Micro tank (all other macro and micro elements)
Acid tank (kept separate so pH can be adjusted individually)
