help w/leafs curling downward

[rpm2nite]

My hops seem to have many curling leaves mostly from 1/3 of the way up and higher. I water regularily and put some 3-10-3 fertlizer on them about 2 weeks ago but the curling was already happening.

It seems to be affecting most of my 36 hop plants (several varieties) the 2nd year plants are 15-22' high.

They also did have some burned tips on them but it's mostly curling now.

I thought this would go away, it's been almost 3 weeks but its not changing.

Any ideas?

leaves rolling and then browning can be zinc deficiency according to the brewmasters garden.....they say add azomite(dont know what that is) or wood ash, and boost plants with seaweed spray.
