I posted my question in Tomato Growing,

https://www.houzz.com/discussions/6105455/disease-window-sill-tomato-plant-leaves#n=0

I will post here as well. Sunny window sill tomato volunteer. Looked good, now, not so much.

can anyone offer ideas as to what’s going on? See pics. volunteer seeding from plum tomato.

with readers on, I cannot dis earn any insects. It’s growing in a pot shared by a rosemary plant.

Think this is a deficiency? Pathology? Insect? I’d like to try to keep the plant if possible. It’s in my sink now. I’ve sprayed leaves with water.

Thanks
