Pls help I’m so confused by my jade plant 😭 when this started months ago I thought he was getting scorched from the sun so I moved him to less sun, but it kept happening. Now I have him in a window with only indirect light and it’s still going on. Then today I found one of the undersides of a leaf looking like this. I also don’t know if the scaliness on the stems are normal?? Any advice is appreciated 😣
