Brassia Spider Leaf Spot Problem

[allars]

I have a Brassia whicch I have had for a very long time. Over the last month it has shown signs of distress. I thought it was an environmental problem, since I live in SW Florida and it has been much hotter than normal. This Brassia lives on my lanai and gets bright light thru the screen for several hours, with the same regular watering and nutrition it has been receiving for years while thriving. I am stumped and dont want to start indiscriminately attacking it with chemicals. Any and all suggestions are greatly appreciated. At this point it is an old friend and needs my assistance, Thanks in advance, Photos below

Which Brassia?

Has it been hot and dry? That could be spider mite damage.

Estacion, Thank You for the reply. I have had this plant for a long time not sure exactly which Brassia it is but the flowers look identical to caudata. It has been dryer than normal and I may have been a bit less regular watering because of work. I have used soap(Dawn) as a quick treatment while waiting for a exact diagnosis. If it is spider mites, I will up the treatment. Do you have a "go to" spray I should try. Thanks Again
