It looks like bone meal to me, ontop of the potting medium. Like suggested, pull it out to check the roots and to see how broken down the medium is. For me sometimes, cymbidiums will also get that on their leaves due to their roots being in bad shape and the plant is stressed. Sometimes the leaves will just spot like that though regardless of how good a shape the roots are in. Overall I think your plant looks healthy and if you decide to divide it, it looks like it may miss a year of flowering because it looks to have only 5 p-bulbs (if divided, leaving you a 3-bulb and a 2-bulb division). I personally prefer growing them in 10 or 15 gallon pots so they don't tip over and the flowerings are much more impressive. Remember, Cymbidiums love to be so pot bound they are practically, and sometimes literally, breaking out of their pots.
