Great article! I find that sometimes water sources are sometimes to blame for leaf margin browning, especially if plant is forming drops of moisture at the leaf margins when heavily watered in high humidity settings. This is called guttation. Well water and some municipal water sources can contain excess minerals and substances that can cause leaf margin dieback.
