calculate ppms from your labels.. see what you've been giving.. you may find you provided plenty of those things and still show symptoms of deficiencies...
pH, concentration and ratio of the elements provided are all equally important factors. i'd suggest investigating the stuff we control first - pH of what you water, pH of feed, pH of runoff. EC of runoff. calculate PPMs of fertilizer. this will allow you to further deduce what's wrong in addition to a leaf symptom chart.
symptom chart, nute spreadsheet linked in my GD profile comments, check them out. 6.5-6.8 even 7 is okay in soil. 6-7 being widest range you want to work in.. anywhere in that range you'll be able to find a concentration and ratio of nutes that works well.
i can speculate.. but without that info, i could harm your plants with that speculation. my best bet -- trace element issue symptoms, but rarely that.. so, i'd go with pH being out of whack.
