I don't know what is happening to my Turks Caps, this started about a month ago on plants that are fairly distance from each other in separate "rooms". The surface of the foliage looks like when you sprinkle droplets of baking soda mixed with water on a car battery. The underside of these "bubbles" are concave. These are well established plants. I've never seen anything like this. Does anyone know what I should do to stop this?
