I found a very useful (and very old) pamphlet entitled "What you should know about electroless nickel plating" in my file. If the company hasn't changed names, check Electo-Coatings Inc. (Morage, CA). Good luck!
ASTM A380-99 on stainless steel passivation cautions (A2.6) that "Severe pitting may result ... if concentration of metallic salts becomes too high (and that) concentration of iron should not exceed 2 weight %..." Is there a simple titration procedure I can use?
