My Brassia Rex Sakata has doubled in size (leaves only). All the leaves are now covered with a brown substance that looks like cinnamon dusting. Even the new growth has this cinnamon like coloring. The leaves are strong and don't seem to have any fungus or rot, but I have no idea what this discoloration is that is on the leaves????? Should this plant be treated? I would like to find out what this problem is so I can possibly right the wrong. At the moment I have isolated this plant hoping someone could help me with my dilemma. All leaves look strong and vigorous except for this cinnamon coloring.
Please help.......Thanks....Faz.
