Catasetum troubleshoot again [bumpy leafes and small tears.]
 

Im starting to fear this is a sign of spidermites. I have another catasetum next to this one but it doesnt show any sign of wrinkle as much as this one.
leaves remaining narrow and a few sign of white spots (or tares?)

My guess is spider mites. Thats how mine look after the mites get to them

Your low humidity means spider mite attack will be routine. Spraying the leaves with plain water every time you water will help control them
