Disease ID needed - I'm stumped
I've looked at a bunch of resources, and I can't identify this issue. Started on just a few lower leaves of a Sungold and now spreading throughout. I'm in southern California, growing in 15-gallon grow bags. My plants were doing fine and then we had a long period of cool rainy cloudy days, so I'm wondering if the soil stayed waterlogged for too long, though I thought my mix had good drainage.
Any idea what this is and what to do about it? Thanks.
