i have these very small almost microscopic bugs on my fan leaves and really on the under side of them. its causing my leaves to turn an olive/pale green with little speckles of black, before they brown crispy then fall off..ive been using neem oil and it does appear to be working a little. can anyone shed any light on my plight
without pics its hard to tell but to me it sounds like you have spider mites, neem oil kinda works but azamax works better.
