The way I've been handling it is this...and please someone correct me...
I save any lactic acid additions for the mash after checking ph. And then only about .5cc or 1cc at a time, rechecking ph after 10-15 mins. I do a constant recirc mash.
I treat my entire water volume (mash/sparge waters) with any salts/etc before I do anything, this includes campden tabs for chloramine. Then I pump mash water to the mlt, and sparge water to the hlt.
