New Cymbidium got it yesterday. I’m wondering if I’m giving it too much light. I thought orchids were supposed to change slowly but this one’s leaves seem to be already much lighter than yesterday.
If the change was abrupt, back off a bit. Cyms want a lot of light, but if it was in a place where it wasn't getting a lot, it needs to be increased slowly. The darker leaves still look fairly light - the goal is a sort of lime green. In general, anything that I get shipped to me I introduce to light gently over a couple of days since it was dark in that package.
