Does anyone know anything about these dark spots on the leaves of my basil? It's in a container, in a location that has been good for basil before. The plant was doing fine, but now in the last week or so I've seen these dark-colored spots appearing on the leaves. Seems like they're heaviest on the upper leaves, but also present on the lower leaves. And increasing! Unaffected portions of the leaves look healthy, growth is still good, but I'm wondering what's up.
Any thoughts will be very appreciated!
