Can anyone help me with what is going on with these leaves most of my vines look good but a few have leaves that haven't seemed to open
And seem shriveled thanks

Has anyone sprayed Roundup or a knockdown weed killer with the active ingredient 2-4-D? Even a small breeze can carry it a fair distance, furthermore, if I'm not mistaken, 2-4-D creates a vapor barrier that lasts for a while.

Classic 2-4D damage from a lawn weedkiller or neighboring farm. Hopefully they will grow out of it.

Man! I didn't even think of that because I never use it. Awhile back they were killing off a yard nearby. Thanks for the help
