| I have a couple of Oncidium hybrids that have this wrinkled leaf problem.
The main reason is lack of water intake. Keep in mind this could be from a couple of things.
One would be underwatering. Easy to fix.
Two would be overwatering. This would cause root rot so that the plant would be unable to take up enough water.
Three would be lack of humidity. If the humidity is too low this can also happen. To raise your humidity put them on a humidity tray.
One of my Onc. that have this wrinkled leaf also bloomed this year from the wrinkled section, so there is still hope for the growths.
