Pride before a fall?

I was so pleased by the early growth of the Toms. I was about to tell the Co-op how good their bags are. Most of our 10 or so varieties are still lush green, albeit showing some change, but all the Gardener's Delight, the first sown, are not at all happy. Not the often seen veining, but a general yellowy-brown, with browning edges. Difficult to show. They've  had a spray of Magnesium but no feed yet.
