Just wanted to say please keep us posted on what happens with your tomatoes and if they recover! I had a similar problem with the bottom leaves on my tomatoes curling all up and it worried me as we live right by a corn field and they sprayed the field with chemicals, I wondered if some got on my tomatoes but they seem to have recovered, so as Charles says it was probably “leaf roll” from when the nights were cooler where I live. Or maybe it was chemicals either way they seemed to have pulled through! But would love to see how yours do!
The pictures I have posted show one of the leaves that I didn’t trim off the plant and then the top of the same plants completely healthy (you can also see how close the corn field is!) so good luck I hope your tomatos recover good!!
