@Figgy;
We draw our water from a aquifer and it's hard as hell (830ppm) most of the white residue is prob. lime.
That's our trouble, I have to chuck my root pouches after 3 grows because the walls are rock hard with lime.
If your water source comes from limestone cal def could easily be the prob.
Check your runoff ph.
