I agree with Scott about the herbicide drift from sprayed lawn or pasture, but check also the fertilizer, which you have used.

I have seen many photos of this type of tomato growth happening in Finland. Suspects are ecological fertilizers made from stuff called vinasse or the ones containing molasses. Both can be made from sugar beets and to my surprise sugar beet fields are commonly sprayed with broad leaf herbicide clopyralid.

I encountered this problem few years ago, when I used such fertilizer. Now there are many European brands selling these "ecological" concoctions, which may contain herbicide residue.

I have seen a lot of warnings about tainted manure, but the plant based fertilizer are no safer. Sad thing is that the manufacturers do not take the issue seriously and many gardeners have blamed weather or some other conditions. I do not dare to use any natural fertilizers in my garden anymore, because I am so afraid of the possible herbicide contamination.
