All three of my plants are running into similar if not the same problems. The Colorado cookies is my oldest girl, she’s has a yellow/brown spots mostly at the top/new set of leafs. Same as my other two girls which is sour orange liver and Livers n cheese. The sour orange is suffering a lot more than the cheese. The cheese is actually doing really good, she’s not showing as much signs of deficiency or excess like the other two. Anybody can tell from the pics or has an idea of what my problem might be and how can I fix it?
