I do see signs of disease. I would be sure to apply a light fungicide to avoid any issues.
Also worth noting- Some potting soils contain too much nitrogen for this plant. These flowers usually reside in poor soils with really good drainage. I would opt for lighter soils, or mix orchid and cactus mixes into your soils.
Watch watering, as well. Make sure that they dry, thoroughly, between waterings. This drought resistant plant will not want to be moist, consistently.
