The plant was growing well for a few months but in the last month or so the lower leaves started to yellow as the plant continued to grow rapidly. The rate yellowing and dropping of the leaves is starting to overtake the new growth.
I live in the Middle Eastern desert, I keep the plant outdoors, it receives full sun from early morning till early afternoon. It is adequately watered. Just dealt with a bout of spider mites and whitefly with daily monitoring and treatment.
I am desperately trying to get the plant healthy before the winter months start to set in.
