They look pretty good to me. You're lucky...I'm just now starting to see shoots coming up.
Sometimes, direct sunlight can cause spots on the leaves. If that's the issue, it's not big deal as hops love sunlight.
The only other problem that would cause spots like that is lack of nutrients. How often are you watering? More often than not, overwatering is the cause of most peoples problems. You can flood the roots and starve the plant of oxygen. If you feel like you're watering too much, just cut it down a bit. The soil should be moist, but not soaked.
Also, have you added any fertilizers? You may want to think about adding some slow release fertilizer to the base of the plant.
