Cold Damage / Cell Collapse?
Yesterday I sprayed two Phals with an alcohol/soap/water mixture in order to kill some aphids. This morning, some of the leaves on one of the phals look like they didn't take it too well. I'm thinking the evaporation of the alcohol caused localized cooling and resulted in some cold damage - does that seem correct? To be clear, this textured appearance literally showed up overnight. They were not actually exposed to cold air.
EDIT: looks like I still can't post a picture - not sure I understand this rule, new members are probably here because they want to share pictures of their collection, or ask for help with a problem that a picture would be super useful for.
The leaves look textured/pitted. Like a gritty sandy texture.
