I thought at 1st that the plant was having trouble with some fungus or some other malady but soon realized it was the color of the banana trunks in your pics. The color was sparse at 1st but each new leaf got more and darker color. After each leaf fully develops the color does not spread any further in that leaf. It is only on the petioles and what is now the trunk. Definitely not a disease. I was hoping for that beautiful color, shown in your pics, too but was surprised to see it so early. Plants are still growing strong but have been competing for light against my AeAe and Florida so are not getting all the light I would like. Will move them to my greenhouse in a few days.
