Orchid Care for Discolored Leaves
Reddish or discolored leaves at the bottom of the plant (the oldest leaves) are most likely a natural process by the plant to discard mature leaves and produce new ones.
Only be concerned if you observe black soot on the leaves which may be mold. If so, clean the leaves with Neem Oil, an organic remedy found at any garden center. If your orchid develops a yellow spot in the middle of a top leaf, this is probably a case of sunburn. Move your orchid to a shadier location and remove the damaged leaf.
If the foliage on your orchid starts to appear dull or if the edge of the leaves start to curl or new leaves emerge deformed, then this is likely the result of low humidity. If it is summertime, you are welcome to move your orchid to an outdoor shady location for some natural humidity otherwise you can run a humidifier in the same room as your orchid.
