Tomato just got checked.
The plant is still setting and ripening fruit, so this does not look like a severe decline. The main issue visible is leaf curling and some dull, cramped foliage, which fits physiological leaf curl in potted tomatoes outdoors. This is usually triggered by hot sun, irregular watering, root restriction, or recent stress. It is less suggestive of a nutrient or disease problem because the plant is still productive and I do not see strong mosaic, severe spotting, or strong nutrient-burn pattern.
Stabilize moisture and reduce stress
Keep watering consistent and deep, and avoid letting the pot swing from very dry to very wet. If the plant gets blasting afternoon sun, a little midday shade can reduce curl. Remove only dead lower leaves; do not heavily prune a fruiting tomato right now.
Also possible, but less likely
What would prove it
Watch new growth for improvement
If this is physiological leaf curl, new leaves should come in less curled once moisture and heat stress are steadier. If new growth becomes yellow, stunted, or sharply twisted, reassess for virus or root problems.
