Is this sunburn or a watering issue? These spots turn crispy, papery brown after they appear. I live in Southern Az, where temps are currently 105. These are potted plants that receive deep watering once every 6-8 days (top 2 inches are usually dry by then). Well-draining mix of soil, bark, perlite. It does receive some direct sun in the afternoon for a few hours, but relocating the plants is not an option at this time. This was not an issue a few months ago during cooler temps, so Im stressing about it right now. Originally by u/Sonoran_Otter on Reddit: https://tinyurl.com/2cb8cn58
