“The top growth is doing the interpretive dance again.”
This tomato looks generally healthy overall, but the newest leaves are tightly curled, twisted, and a bit distorted at the top. That pattern is most consistent with herbicide drift or accidental exposure to a growth-regulator herbicide rather than a simple nutrient problem. Tomatoes are especially sensitive, and new growth shows it first. If no spraying happened nearby, the next most likely cause is heat or water stress triggering physiological leaf curl, which can make the top leaves cup and roll while the plant otherwise stays green.
What to do today
Keep the plant unstressed and watch the new growth closely. If there was any herbicide use nearby, stop all spraying around it and avoid adding extra fertilizer right now.
Also possible, but less likely
What would prove it
Check whether the next flush of leaves normalizes
Healthy new leaves should emerge more normally if this was temporary stress. If each new leaf is increasingly twisted or stunted, rule out herbicide exposure, mites, or a virus.
