I am amazed that your og was so low. I work in gallon batches with just juice and honey, but this last batch I did with 1 gal. of juice and 6 oz. of honey gave me an og of 1.068 which would be close to your ratio unless I am missing something. If I were you at this point, I would cold crash it, take it off the lees(secondary or whatever) and let it sit for a bit to mellow. Then see if it needs some back sweetening.
