Is it normal to have orange rings developing on the node creases? I saw it on another picture for dendrobium. Wondering if this is rust or something else.
I think what you notice is part of segment ring thats dried up over time. when the segments are fresh they are green and then yellow. as they get older and more exposed to light and air, the segment rings turn orange.
Thanks guys. Thats perfect because thats exactly how it went. Started green then yellow then orange. Just seemed the orange changed overnight which is why i noticed
