The water will pickup iron and chromium ions during its brief contact with the coils. What I would say is this: Would you drink the A/C condensate? If the condensate is not potable, would you use it on your Orchids?
I wouldn't worry much over the brief contact water will have with stainless steel. The water condenses on the steel and drips off in a few minutes. Much less contact time than my (acidic) coffee is in contact with my stainless steel carafe each day.
