I need some help diagnosing what’s happening to my angel plants leaves. There’s these sort of burn marks that keep growing and spreading across the leaves. My guess is something to do with watering? I water this plant about once a week but I usually just look for signs of wilting for when to water it. The plant is being kept inside a plastic pot with drainage inside of a decorative pot without drainage. The plant gets minimal direct sunlight each day - probably less than 1 hour max if it’s sunny out. Otherwise it has bright indirect sun for most of the day. Any help is appreciated!
