Anyone ever get yellow lower leaves?  Nitrogen deficiency?  Disease?  Anyone?  Anyone?

It looks like the vines could either have powdery mildew, a virus, or nitrogen/potassium/phosphorous deficiency.  By comparison to these pics:

It looks more like a nitrogen deficiency.  I treated with a disease spray and also fertilized.  Anyone else seeing this?  Anyone? Nitrogen? Anyone?

I wish I could help you with this one, but the page you linked to has more info than I can offer.

My established vines are tall and huge, and my new ones are sad and small.  But all are still  a healthy green.

Yeah, it's not patterned like a virus would be, it doesn't look like mildew, and it is only on the lower foot or so of the vine.  We shall see if the fertilizer helps.  Maybe I should pour some homebrew on them.

My vines are green and healthy looking, but slow growing.  They are only second year, but the tallest of the fuggles is only about 3.5 feet tall now.  The cascade is coming along, but not too quickly, maybe 1.5 feet off so far.  Maybe I need to fertilize, though I planted the rhizomes in a mixture of peat moss, manure, and top soil just last year.  It could also be that they are just second year plants and on the edge of a tree line, so they only get heavy sun from one side.

I've got some yellowed leaves at the base of a few and am using a copper-based fungicide. Seems like they'll be just fine and produce as nature intends them to. I think Jamey had mentioned stripping off bottom leaves for increased air flow, decreasing soil borne pathogens, and minimizing disease-ripe conditions. Last year I had some bines that took a beating but still yielded so it seems that despite the odds they still want to flower and follow evolution's plan. We'll see come August...

Very cool.  I saw the cones where coming out on mine last weekend but they still are pretty small.  They are maybe a little bigger than the fingernails on my thumbs, but I haven't checked them at all this week.  I've attached a picture from Saturday.

Hop growth update:

Cascades: not yet cascading.
Challenger: challenged.
Willamette: on steroids.
Nugget: first year bumper crop perchance?
Goldings: no gold medals for these lame ducks.
Mt.Hood: Mole Hill Hood.
Super Skunk Weed: nine feet tall. (Reality check. None growing, Just checking to see if you've been paying attention)
Crystal: the little engine that might be able to.

Mine got damaged in the hail storm earlier this week that we had in Stanardsville.  Hopefully they will recover.  Prior to this, the highest they got was about 3 feet off the ground.  I had fertalized and that seemed to help, but now Mother Nature really damaged them, along with destroying all of our garden and most of my wife's flower beds.

Sorry to hear about the hail storm, Tom.  I am sure they will still put out for you.  My Kent Golding suck as well.  They just don't grown well.  Cascade seems to be the best out of 6 varieties I have grown.

So, yeah the whole yellowing of leaves was a nutrient diffeciency. I added fertilizer and within 2 weeks the leaves turned back green.  My new replacement jumbo cascade hops is keeping up with the cascade from last year.  I am seriously considering ripping everything out except for cascade and replanting all cascade next year.  I think in the long run it will be worth it.  Especailly for a harvest dry hopped IPA.

Doc - A wet harvest ale sounds really, really good.

Greg - My Nugget vines have always done well.  I can't explain why other than to say that I think they just are a very hearty variety of hop.  I got a mini harvest my first year, and that certainly isn't going to happen with my new Cascade vine.

I've attached another picture of the cones on the Nugget.
