Hi all, I recently got started in bonsai and got this Dwarf Kingsville Boxwood from a local bonsai nursery. I started noticing some bronzing in the leaves, and I thought it was because of too much fertilizer, which I removed. However, last week I really started to notice these scale-like things on the leaves. They don't move as far as I can tell, and they're on both the top and underside of the leaves. I think they are on the trunk as well. I can't get a close enough shot to see the fine details, but I'm hoping someone here has experience with it. No other bonsai around it have the same issue. Any ideas for ID or care? Thanks for your help!
