dry spots on basil

dry spots on basil

So, my basil plants (Genovese and dwarf) developed dry spots on their leaves. They are outside in pots and the weather's gotten colder and damper after the lovely heat and sunshine, so I know they aren't having the best of times. Are the dry spots due to that, or is it something that can be more precisely diagnosed? Thanks a lot for the advice!
