sick avocado plant with yellowed leaves and rust spots
I have an avocado plant that has suddenly (in past month) yellowed every leaf and is rapidly becoming covered with rust spots. It has had a problem with scale in the past and I'm wondering if this is related. It also had a dose of Schultz's houseplant food about six weeks ago, the first fertilization of the new year. Any suggestions any of you could make would be greatly appreciated.
