This year I have a new problem with leaves dying. It seems to be affecting the oldest growth. It starts out as this:

Then eventually is progress to this and the leaf dies.

I spray Eagle and Daconil fungicide every two weeks. The plant is pumped full of Merit and gets sprayed with triazicide every two weeks. I can’t figure out what could be causing it. Thanks for any input.

You asked for any input....yes ? Stop over-dosing your plants with all the complex chemicals. Let them just....be plants. Kind of like, let a puppy be a puppy. It is common for those early leaves of many plant types to fade and whither as one thrusts a substantial transition into that plant's life, i.e., going very likely from indoor propagation to eventual installation into real, live soil and full exposure to all the elements.
The early leaves have done a bunch of "work" to get your plant rolling along, and then they surrender their need for new nitrogen and pass it along to the more active growth end where young new leaves are being pushed out. Not that big a deal. (I have not looked at your pictures, sorry)
You might cleanse your plants every week to ten days with product called 'Plant Wash' and follow that with a committed foliar feeding program in early evening with something like a fish-and-seaweed solution. Add plenty of good, mature compost to the soil at the stump area and in places where you are burying the vine.
I could share more, but I will likely be scorned because I do not emply any intense chemical practices....and yet I have plants and vines that are doing just fine. Perhaps it's just the drier air out here at my elevation and location.

I'm with Mark...classic sunburn! support some remay material over newer growth for a few days to a week and see what happens. Older leaves don't tend to burn as easily. Good luck!

On second look, those do appear to be older leaves...still thinking it's sunburn.
