What is wrong with the leaf and should I be worried?

Mine is on my condo deck so it doesnt get a ton of direct rain but I'll give it a shot. Thanks

My Centennials have the same brown spots on the lower leaves. I have read that many commercial growers strip the bottom 2 to 3 ft of leaves anyway, so I'm gona let mine ride for now and just trim the brown ones. I also read that the first year after transplanting can cause brown leaves because of root tangle, and will sort itself out after a couple months.

They are 2nd year(first year in a 2 gal pot) and are already 18ft tall. Whatever it is, it's not effecting growth at all.

First picture: Could this be root tangle or something else? These are second year plants, first year in the ground. I'm currently growing these in the Willamette valley. Both my Mt. Hood and Centennial have this browning of the leaves, their growth is bushy, they refuse to climb, and the bines stay very thin and don't thicken like my other plants that are doing fine. When I transplanted these I really tried to break up the roots.

Second picture: My Willamette for comparison is almost halfway up the rope.

hum, no idea why they would be bushing up unless the top bud of the bine was cut off. I'd try just trimming the brownest leaves and see how it goes. Maybe someone else will jump in with a better solution.

I wouldn't read too much into the situation. Some varieties do better than others with taking the whole 'terroir' thing into account. Those lower leaves that are turning brown seem to be 'old age' in my book as it happens to the lower leaves no matter what variety I've grown, some worse than others. I do know that Mt Hood grow well in Mt Angel/Silverton at farmer Butsch's place. As long as the upper portion of the vines look good, you're in business!

Leaf update, so after trying two different chemicals I found that a combination of miracle gro and soap water spray did the best job. The neem oil that I was using was missing the neem ingredient... yay Lowes

But here is a healthy plant update

Another update: the hops are growing strong, I think I will have a great first year harvest.
