Odd. What is the content? I guess it has iron EDTA? That would be the only explanation for the colour. It should contain either sulfate or nitrate of Ca and Mg which don't have a colour.
Not sure why they contain iron, it's boron which should be coupled with Ca against BER.

Does your water contain any Ca? What is the ec of just water? It's unusual to have so much ber.
