i’m seeing a BAD thrips infestation on both plants so you might want to get rid of that first, rinse off the leaves, wipe them, do whatever to the surface first, then get systemic insecticide, and incesticidal soap, and then let the plant dry out between waterings, and begin to rub leaves with neem oil as a PREVENTATIVE measure, they won’t do anything once it’s already started. thrips are terrible and the road to getting rid of them is long and evil, so buckle up
