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

[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.
