| purple tinged catt leaves The newest leaves on my Iwana 'Apple Blossom' orchid are turning a purple color. It is darkest where the leaf axis is and gradually lightens. The plant is in a south facing window on a humidity tray and gets a good amount of sun. There are two other orchids with this on. A rescued Oncidium from Walmart and a new aquire form Carter and Holmes. Both of these plants don't have this purple tinge. The plants are watered once week and fertilzed weakly every other week. What could cause this or is it just the cultivar. |
