I never did a soil test when I planted mine but It was just local dirt nothing special. I mixed in some potting soil and manure but not alot. I think drainage is important with hops. The soil I used did have a good bit of clay in it which I would think is not so good but they are doing well. How many rhizomes do you have out of the ground? I'm not an expert on plants by any stretch of the imagination. I kind of worked with what I had some free dirt from a job site and cheap potting soil and manure from the local kmart.
Where did you get your Rhizomes? They might be willing to give you some advice. I got mine from freshops and they were very helpful and have an informative website.
See the hops growing section Perhaps email them with some pics
I wish You luck Once they start they get massive
Here's a pic of mine I think its been 3 years now
