“Glazing” on old Thanksgiving cactus? I recently found a very old looking Thanksgiving cactus at a thrift store. It’s a little beat up but seems to be healthy overall. There is this totally bizarre thing going on with many of the leaves though, and I have no idea what it is. I’ve looked at pictures of sunburn, pest damage, and diseases and nothing seems to match. It literally looks like areas of the plant are glazed or have a brown oil slick on them. If you look closely you can see patterns that don’t seem uniform like you would expect to see with sunburn. Any clues at all would be appreciated. It doesn’t seem to be hurting the plant I’m just stumped. I can’t speak to previous care regarding watering as I just got it but again it seems healthy minus some cosmetic issues. It is in a pot with drainage. Light-wise it currently lives outside in bright shade. Originally by u/Tarlu on Reddit: https://tinyurl.com/26tefwql
