Would anyone know what causes these spots? It’s on several of the leaves now and I just want to know if I’m doing something wrong! I’m trying to bottom water a lot because I was having a tiny fungus gnat problem so I think that lead to a bit of under-watering for several plants. Nothing too severe though. I also wipe down my leaves often to prevent pests & I used alcohol once for some mealybugs. Could that be the culprit? It looks otherwise healthy to me.
