Can anyone tell me what these brown splotches on my ficus elastica/rubber plant mean? I just wanna double check that it’s not a sign of something like thrips, edema, or rust. I’m new to this plant, and I believe they all arrived with this on the underside of their leaves, but only noticed it recently on my ficus elastica burgundy, which led me to checking the others and finding the same patterning on them all. Aside from it, they’ve all seemingly been healthy, and all opened new leaves within a week of bringing them home. Please let me know if it’s just a previous watering problem. Any help is very greatly appreciated ☺️.
