Tenuipalpus, False Spider or Phalaenopsis Mite control

[Welfkoondo]

Hello:
Does anyone have any experience identifying and treating for Flat/False Spider/Phalaenopsis mites? I am having a very tough time with my Oncidium Intergeneric Hybrids, Phalaenopsis and other orchids with severe yellow stippling on leaves. I tested for virus which were negative and tried many fungicides also negative. I also took samples to 3 professional orchidists who thought it was some sort of insect or mite issue. Even under a USB microscope I can't spot movement, legs, etc. so pretty sure not spider mites. All I see are tiny white specs. Most miticides only label for spider mites, not flat or broad mites, so struggling for an effective control whether chemical or biological......
