Anyone know a good substitute for B-52?

About a year ago I switched from advanced nuts to house of garden. mainly because AN raised their prices too much and were rude/unwilling to answer me in emails I sent them. well a year later and Im not happy. I cant get yield up and want a more complex/complete nut system like AN. but without going all the way to AN. I can find other zymes, root excells, humic/fulvic, etc. but cant find a good B complex. yes, I know super thrive but I want something ment for hydro! Anyone know a good substitute for B-52? any thoughts?
