Spotting on leaves of various orchids
I have some phals and oncidiums and then 1 tiny vanda I have started to worry about and just wanted someone to weigh in on if it's just the leaves or if its actually an issue. A friend of mine suggested the Vanda has orchid fleck. A phal manii of mine has tiny black/brown spots on it as does my oncidium okika. An oncidium yellow Star Golden gambol has some brownish black rings around what looks like a dry spot in the leaf. Please see attached pictures. Any diagnosis and treatment advice would be helpful. Thank you
