I grow it in an earth box. The tomatoes look fine, it’s just the leaves. They get these small speckles of light tan colored dots and then get worse from there, turning yellow and crispy brown. It seems like it mostly effects the older leaves. They get west sun, could it be sun scorch? Or is it something nutritional or a disease?

I should mention I planted it with an organic granular fertilizer in a fertilizer strip. Is it possible it’s already used it up and I need to add more? Should I put a liquid fertilizer in the water reservoir?
Lots of rain? Looks like pretty typical fungal effects. I would just trim the affected leaves on a dry day. My tomatoes’ lower leaves always get the chop eventually
Just chop off the old leaves. If you hand water avoid splashing on the plants. This isn’t unusual as the plant ages.
Looks like late blight
Have you ever tried to grow tomatoes with the plastic covering like that?
Any pests on the new growth? Thrips on flowers?
Looks like you may have a couple things going on. The lower leaves look like spider mites, or some sort of similar pest. Flip them leaves regularly. Then you have maybe some sunscald earlier in the season but nbd now.
