Also, can anyone confirm the AC discharge is the far left discharge with the stain in this photo?
A lot of times it's the condensate drain that gets the stains, because there's some rusting going on in the bottom of the pan below the A/C unit. You don't want to squirt water back into that if it is indeed the condensate drain. Sometimes the condensate drains into the shower sump, which then gets pumped overboard and causes a similar stain. You also don't want to squirt water back into that drain either. You can run the shower and see where that water gets pumped out to determine which thru-hull serves which purpose.
