The other plant in the foreground (cabbage) doesn't look happy either. Could it be spray drift from weedkiller?

Hi, my word Steve you must have blooming good eyesight, all I can see are plants thatlook as if they've been sprayed with weed killer, time I got new glasses I think :-) , Derek.

I would suggest that they have not been watered well enough given they are in raised beds.

My first thought too, but then noticed that just a few of the other surrounding plants seem to have "caught" it too.

That just looks like odd leaves on one brassica to me Stera. so, Dave could this be weed killer spray?
