    Hi all, wonder if anyone has an idea of what this could be on my starfish leaves and is there anyway to treat it.
    Not sure if it is fungal or bacterial but when rubbed nothing comes off.

    It is similar to what happens when the tree gets too dry. At the time, new stems/leaves just drooped and perked back up (recovered turgidity) after watering. A few days later affected leaves turn 'brown' similar to what I see in the pix.

    Right : mine has the same symptoms. It's in a mostly sunny place. My 'Red Trompenburg' is in the shade, in a cooler environment and has almost none of these dry patches.

    Not very elegant, but nothing to worry about I think.
