I'm brand new to indoor gardening but have been stalking these forums for a while and I hope someone can help! I have white spots on my new Chamaedorea plants. I thought they could be mealy bugs but they don't move and no matter what insecticide I try they won't go away! I repotted both about a week ago and it hasn't helped at all. One is worse than the other, which is strange. I don't use tap water and while my fertilizer/soil isn't the best- it's also not the worst in the world, I can't figure out what's going on! I was hoping I could get some advice! Thanks :)
