Welcome to the forum.
I know you didn't post the question here, but I saw the pictures of your vines elsewhere. What did you use to clear the area around your vines? Did you hand pull the weeds or use a hoe or possibly apply a weed and feed lawn product? The vines look like they have an herbicide damage. If you sprayed Roundup around them and touched the leaves or young green shoots, the spray can cause that type damage. It can also be 2,4-D damage (herbicide) from applying a weed-and-feed type lawn product. The vines will hopefully grow out of it, but it sets them back a bit.
Be sure to post your vine questions here also in our vineyard section and we can possibly help you out.
