I had this problem a few years ago and found this to be attributed to an
iron deficiency (chlorosis). Every year I have been using a chelated iron,
mineral supplement and I have increased my nitrogen. I would add some
Miracle Grow Lawn powder (high nitro) in my normal foliage spray and this
really helped.
I believe what you see is an in-balance in soil moisture (too wet) which
deprives the plant of some nutrients. Also the manures tend to breakdown
/ decompose when this was observed........which causes the nitrogen along
the top layer of soil to really be used.
I know some genetics cause the vines to be streaked with yellow, but
yellowing of the leaves should raise some concern. If the veins are yellow
that is a ph problem, to acidic. Look up chlorosis on the internet and
try to identify your leaves with pictures. But the nitrogen additive is a
treat for those leaves.
