Odd spots on Catasetum leaves
 

Hi,

I need advice from Catacastum growers. I discovered some odd spotting/stippling. I checked the undersides of the leaves but there is no sign of mites.

Iam wondering how worried I should be and whether you have any ideas.

I use the old kind of listerine mouthwash....by dipping a cottonball wet and wiping the leaves with it....the alcohol evaporates immediately and clean the leaves of any mites, algae or fungi infesting it.
Hydrogen peroxide will also work....
