I noticed these spots on the cherry tomato today, the closest thing i could relate it to in my NGA book is early blight, i cut off affected leaves, is this blight or some other disease?
It looks like some sort of fungal disease of which tomato plants are very prone too. Cut off all affected leaves and any healthy leaves touching the soil. Get a product to spray the plants called Daconil and keep up with the spraying.
Daconil is about the only thing for tomatoes. Works pretty good. Honestly you can just pick off the affected leaves and the plant will most likely just continue to grow.
You're right, Daconil (chlorothalonil) is definitely not organic. I'm not certain what the problem is but I actually wonder if it could be an abiotic (non-living) problem? Here's an example picture:
