These are cascade hops, I'm thinking they nitrogen deficient. Does anyone have an idea what is going on. These are second year hops, the first year they looked great the entire season. Thanks, JD
Nitrogen deficiency will typically show as a yellowing of the older leaves as nitrogen is pulled from them into newer growth... Since they were also able to produce hops, I'd say that it isn't nitrogen deficiency. That being said, I am not that familiar with hop diseases, so it is possible that it is a fungus as the above listener suggested, or it may be a deficiency in another type of mineral...
