Does this look like fungus or pests on my ruby ficus? I brought her home yesterday, changed out the soil, and the roots look good. These spots are only on this leaf, the rest of the plant looks very healthy.

    They are lithocyst; they are calcium carbonate crystals that form on the cell walls. They definitely are not harmful to the plant, some theory’s say that they improve the plants ability to photosynthesis. They should come right off with a damp cloth or paper towel. If they don’t come off, try using vinegar or lemon juice to help break down the mineral build up. Hope this helps!
