Hi there! I have had a money tree for a few years. Aside from the odd yellowing and dropping of leaves, it has been growing fine and has been in the same location for years. Recently, many leaves turned yellow with dark green blotchy pigmentation which I haven’t seen before. The only differences I can think of are that I used an insecticide on the plant about two months ago and have placed a new rubber plant about 5 feet away, however, that plant looks healthy. If anyone knows what this is or how to avoid it spreading, that would be great! I have just been removing the discoloured leaves so far. Thanks!
