It's easy to see this and think "DRY" as it does get dry and crusty and on some plants it'll be yellow and brown crust. But when it looks like it was dipped in something, when the damage starts showing up from the top of the leaf while the leaf itself is first and doesn't feel flimsy, like it would when dehydrated- it's too much water. For years I kept killing my plants with water. Then someone said "plants can bounce back from dehydration but water damage can only be removed, not reversed", then I learnt that water damage looks and feels dry but it's just dead tissue, not a thirsty plant. I know this post might seem patronising or daft or unnecessary to some people but I know those two things- knowing how water damage seems dry and that plants can not recover from water damage enabled me to be a plant keeper and breeder after years of being a very sad plant killer who kept trying and kept failing. Don't bully me. I know I wish I saw a post like this bcoz a lot of my plants looked like that and I kept doing everything BUT letting them dry. Good luck! ☺️💚
