I have a leaf problem on one of my grapevines (the Black Hamburg). This is affecting the lower, older leaves the most - the edges start going brown, eventually spreading inwards and then going dry and crispy. Initially this only happend on the 2 lower leaves and then stopped, but it now has started again on some of the higher leaves.
The grapevine is planted in exactly the same pot and conditions as my other vines, and none of the others have had the problem. Pics below (including pics of all my vines):
First leaf of the vine:
On the left one of the first leaves with problem more advance. On the right, one of the leaves just starting to show the problem:
Another leaf just starting to go brown at the edges:
Saint Laurent vine (my favourtie vine at the moment):
