Just received this a day ago now, as a gift, and the white splotches (which were on it when received) look almost similar to how bleach would stain your clothes! I see no mites, bugs, no webbing either, the spots aren't on every leaf! I've read many articles and forums and none seem to be exactly what I'm looking for. So sorry if this is a common question; I'm new here / new at "seriously" gardening.
Some of the leaves at the base are yellowing as well, only two small ones, seems to do with uneven watering. But the plant is otherwise healthy. I do know this was purchased from Walmart, if that matters!
Do we know what this could be? Would it be wise to exchange it out for another catnip plant or can I 'troubleshoot' and fix this?
