New to Growing. Have nice-looking plants but all of the leaves are getting white spots on them which are turning to Brown. Took a look very closely with a magnifying glass and could not see anything moving, if it is mites they are microscopic. No evidence of Thrip, should be able to see the bugs or larvae with what I am using. Have not used a microscope to look for microscopic mites. Did not look really flaky like I would expect some of the fungus to look. Any thoughts on what this might be? Basically white spots that turn to Brown and then become a hole in the leaf. Thoughts?eaf.
