I've grown hops in north Texas with some success, but never seen this particular issue.  Magnum hop vines are 4 feet tall looking good, but the leaves have turned light green to yellow.  The edges and veins of the leaves are dark green.  I would include a picture but couldn't figure out how to do it on this forum.  I don't see any mites or other bugs, but guessing this is some type of disease.  Anyone have a similar experience and have a solution or spray or something that I should try?

Thanks... Steve

Sounds like magnesium deficiency. Try some Cal-Mag.

Just a thought, there are several blights which affect hops and discolor leaves. Search for downy mildew and powdery mildew. Probably not what you would see in TX, but both are common problems for hops.

Also, helpful if we could see a picture.
