Tomato leaves browning

Question

My tomatoes are doing awesome this year! Taller than me and bearing loads of fruit. But recently I noticed that the leaves at some of the extremities are beginning to turn yellow, curl downwards and then go brown and crunchy. It only started a few weeks ago but looks like it has spread between plants.

They are grown in medium to large pots with lots of sunlight and some wind keeping them at a good moisture level. I have also pruned the base leaves to increase airflow. Is it lack of soil nutrients, yellow leaf curl virus or something else?

Thanks!

Answer 1

It makes sense that it took a few weeks to spread: this sounds like leaf curl — and it’s no surprise, depending on where you live, considering the extreme weather many areas are seeing this year.
