I planted this grapevine about 2 months ago. The vine has been growing well, but now I'm seeing some problems. The leaves don't look green and healthy. I've looked all over the web but can't find a description of what I'm seeing. The grape is a crimson. I'm in the Bay Area and the plant is getting plenty of sun. The weather has been a bit cool, but not cold. Can someone diagnose from the pictures? Do I need to pull this vine?
