Grape Vine issue (forum)

Kielvale starts with ...
Hi viewers. I recently planted a new Chambourcin vine.
It is looking rather unwell. The new growth is stunted and brown.
Unsure if it is over watered or has some other problem, or if it is normal.

I also planted an Isabella, It is looking great. Similar location and care.

It looks a bit like thrips or mites. You may be able to see tiny bugs or larvae ??
Thrips often under the leaf on the veins.
Maybe Rust Mite ??

Due to the amount of rain we have had, I'm thinking Downy or Powdery Mildew.
it has also been very hot, intense sun and humid these last weeks.

I couldn't see any thrips or mites. But there is definitely some sort of disease on the vine.

I tried some Lime Sulphur at 50ml per litre. My vines are now looking very much worse for wear since I applied that Tuesday afternoon.
I will give them some time to recover and maybe try a copper based anti fungal.

Have a look at wsu2006 post from Dec 6 for a picture of Downy mildew. Yours look different.
