So I have two large but young Early Girl tomato plants that have just begun to bloom, they looked healthy and robust up until a few days ago.

Now suddenly all the new growth, the crown and the new side shoots lower down have crumpled bright yellow leaves. They aren't wilted. They aren't curling. They look like the leaf veins are shorter than the spaces in between and they are just puckered.

I see no evidence of insect damage, they are planted in compost, and sheltered from rain. It looks like nothing I have ever seen.

What are the odds that the bee killer that got used above them is the cause, and then, what are the odds that they will recover?
