So I decided to add CaCl2 to my liquid fert mix yesterday, rather than the usual dry dose. I took out the MgSO4 and mixed it over with the CSM+B to avoid precipitation issues.
The mix was standard EI stuff outside of the CaCl2; KNO3, KH2PO4 and K2SO4. Upon dumping the weighed fertilizers in to water, the mix began to bubble, and heat was produced enough to warm the glass measuring cup up. From there, a nice crusty, flaky precipitate was produced that seemed to be made from fused granules of CaCl2. Out of curiosity, I heated the mixture up and stirred it for a while; zero solubility at boiling point, though the precipitate broke down in to a fine silt.
What just happened here?
