Can't really tell from the picture, but if it's a magnesium defficiency the leaf starts to turn yellow (with the veins staying green). Magnesium is really important for chlorophyl production hence the yellowing.
Blight usually has a yellow "halo" around the black/brown spots and the leaves start to wilt.
Kestrel were the first 2nd early variety I grew. As Netherfield pointed out they make wonderful jackets if you leave them in for a long time.
