Well, I would probably suggest pruning the leafs (if they really are indeed infected) other then that, I'm not exactly an expert. I've read (on here a lot) that you can basically prune all the leafs off the first couple of feet, because they tend to get eaten/infected the most, which is what looks like is the case for you. It looks like your first years have buds on the cascades, I'm jealous. Mine don't have any yet

mine have looked like that for as long as i've been growing them. i just reckon it's just a normal weathering process as it usually occurs on the oldest leaves. as long as the actively growing portions look healthy, go have a beer and enjoy life!

I think you might be lacking in a nutrient, but I lent all my books to a friend.
Freshhops has pictures of common issues, could this be a Potassium Deficiency?

I'm not an expert by any means. My leaves looked liked yours last years and I adjusted my soil and none of my plants have this issue this year.

Hope it helps and hope someone with more experience than me chimes in.

I've been having the same problem. You can read the thread here. http://www.homebrewtalk.com/f92/nutr...ciency-183811/

General consensus was to hit it with fertilizer.

Thanks for the replies.

Bosox - they are budding pretty well! I have two cascade plants, both are about 9-10ft in length and have a fair amount of buds. My chinook and centennial plants are only about 4-5ft tall and have no buds as of now. Both the chinook and centennial took about 2 weeks longer to pop out of the ground than the cascades, so im still hopeful.

I am looking in to nutrient deficiency. I hit them with some miracle grow about 2 weeks ago. Think this should be applied every week? I use the granules and mixed 1.5 scoops for 2 gallons of water.

You shouldn't have to add fert every 2 weeks but 1.5 scoops in 2 gal of water seems to be pretty diluted. Maybe your scoop is bigger than the one in my miracle grow but I typically do half a scoop for 1 quart. The water has a blue tint to it (pink last year...maybe I have different stuff this year). Also, I have read it is best taken in when applied to the leaves and not the soil. I put mine in a spray bottle and spray the crap out of the leaves early in the morning.

I would do another application and see what happens.

I think a scoop is 1 tablespoon, so 1.5 tablespoon to 2 gallons of water. I can up it next time, and will also apply to all the leaves. Thanks for the advice

Yeah, I think you're right on the 1 scoop = 1 Tbsp. I guess just follow the directions on the box. Some people like to go a little under the recommended amount which I dont exactly understand. Hops are more fert hogs than a 'mater plant is gonna be so why go less than that?

Some of that looks like spider mite dmg - have you checked the underside of those leaves? I would prune them and then prune on up the bine quite a ways...at least a foot or two.

Cheers
