My hops are showing signs of Phosphate (P) and Potassium (K) deficiencies. I don't have photo's of the actual leaves but they have the same look as these;

More specifically the Potassium (K) example.
On a whim, I picked up a soils test kit at the local Home and Garden. It's a Mosser Lee "Soil Master" test kit (RM# 31190) http://www.mosserlee.com/howto/soiltesting/index.html
Test result level equivalencies are given here;

Per my test, using distilled water, I have resulted the following;
pH = 7.0, N = Low, P = Medium, K = High
WTF?
My plants show clear sign of K deficiencies but the test results determine I have the equivalent of 160lbs/Acre of K in my soil. Could this be a K poisoning effect?
I have read that the effects of too much macronutrient can mimic that of too little in horticulture. Is that happening here?
And what of the levels of the other macronutrients? Should I be adding a high nitrogen fertilizer at this point? A fertilizer blend of say 20-10-5, or something?
My garden is approx. 150ftsq or 162.6ftcu.
Someone please help me?
