you have spider mites...dont worry it happens in every hopyard. I use two types of spray: zeal or Vendex miticide, you can order online. If you turn the leaves over you will see the tiny bumps clusted together. Good Luck
Hey Everyone, glad to be part of the community. Would love to hear from some brewers in the Metro NY area. Have a hop farm in Orange County, NY and welcome anyone in the area to come by for a visit. Your can "pick your own" hops in August. Looking forward to some good discussions and new ideas.
