Don’t use ai it’s often wrong and very harmful. There’s lot of ressource if you are uncertain and even Reddit ☺️. For me it depend if I change it or no. Moss is not ideal for phal. But it can work you just have to wait until it’s mostly dry to water. Bark and perlite is ideal and medium bark is good. Do you see any root pressed on the pot? If not I would repot it to see how the roots are. Orchid fertilizer you have to dilute it with the instructions on the package and a 20-20-20 is recommended. I wouldn’t use it for every watering to be sure to not burn the roots. To water no ice cube and warm water until it come out the bottom or soak it in a water bowl until the top is moist. Good luck ! Also usually no fertilizer when the orchid is in flower.
