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

[james lahti]

ANTHONY

sure looks like potassium deficiency to me. i have had the same  
problem with my pinot noir.
whack it with a foliar spray of 1-2 litres of k-fight 0-0-25 and  
throw in a bag of epsom salts ( 20 kg)
do it now and then 1 week from now - don't spray until it drops below  
20c or you'll burn your leaves.
all the above is based on a spray volume of 1000 litres. YOUR ALSO  
GOING TO HAVE TO LIME THAT
SOIL SOON OR YOUR VINES WON'T FIND ANY MACRO OR MICRO NUTRIENTS.
ciao,
