Fertilizer Concentrates & Compatibility
Some fertilizer materials interact to form insoluble compounds and precipitates when mixed together in one concentrated solution.
The precipitates fall out of solution, tying up the nutrients and making them unavailable to the plant. Possibly also causing clogs in the irrigation system.
For example, fertilizers containing calcium must not be mixed with fertilizers containing sulfates or phosphates in the same concentrated solution.
