[Growwine] Help to determine cause of Cab-Sev symptoms

[defaria@reztel.net]

   Hi Anthony,

   I am also in agreement with James that it is a Potasium/Zinc
deficienciy. - Last year I had the same problem with a section of the
field. The leaves were resembling yours, and was very worried about
the yellowing. (Yellowing disease crossed my mind) I purchased a
whole pile of Potasium last fall and really laid it on heavy around
each plant this spring. - This year there is no yellowing, and the
leaves are not red-veined as well.

   Quoting Canada Vintage :

	Hello All,
I need help in indentifying a problem I have with a section of my
Cab-sev vineyard. 
 
The leaves are demonstrating a bizarre yellowing and redenning. The
vines are eight years old, and have produced normally for the last
five. However, now these vines have very small fruit clusters, the
vines are not vigorous at all and the leaves start to change color
mid season. 
 
We have run several soil samples and did come up with an unsually low
pH of between 4.5 to 5.0. All other nutrient levels seem to be within
normal parameters. I can send those along if required. 
 
I have attached a few images at

Any help would be greatly appreciated.
