First sign of Late Blight, an almost unnoticeable mark and easy to walk past.
I picked the leaf and placed it between a layer of damp kitchen paper which I placed inside a plastic bag and left it overnight. It was clear it was indeed Late Blight in the morning, but then again so were several other leaves in the potato patch! Not sure if it helps but at least if it were something else such as Early Blight you could rule Late Blight out.
