Hi,
I have three outdoor potted Dracena Marginata that all have small, light spots all over their leaves. I thought that they might be scale, but I can't find any evidence of critters on any of them. The spots are recesses as opposed to being raised, as though they've been chomped on. I've inspected the plants carefully and a few of the individual leaves under a lighted magnifier. Thoughts?
Many thanks!
