It seems, by the look of the leaves, that the problem is lack of water (or excess of it) and not salt build up. By other hand it might be an older leaf giving its soul to the Creator.
Can you give us more photos, especially of the medium and the rest of the plant? And what's your temps and humidity as well as watering frequency?

I am currently using the Phalaenopsis AAA gold imperial mix from repotme. I let the moss get slightly dry before I water again and never let it stay really dry or wet for extended periods. My temps are around 71-75 degrees Fahrenheit and I have it next to a humidifier. I have also been testing the limits of this orchids sun exposure by giving it bright indirect light.
