Orchid green leaves falling all at once Thought it may be shedding old leaves at first but they’re all green.. Worried about my Darwina rainbow stars orchid. It lost 70% of its green leaves within the last hour. The person I got it from said it’s just dry and needs more water, but it also has these white spots that are showing up on the leaves. The spots come off with alcohol but keep coming back. No insects under a microscope. Anyone have any insight they can share?
