I may be too late, but if you are using fresh apples, add pectic enzyme at the rate of 3/4 tsp per gallon to extract more juice out of your pulp, and 1 Campden tablet per gallon to prevent oxidation and the turning brown of your apple juice. Also to get rid of any bacteria, wild yeast and mold, 1/4 tsp per gallon of potassium metabisulfite. But if you are using store bought cider or juice ( which is filtered cider ), make sure that it does not contain any sorbate additions. The sorbate will inhibit your yeast growth and putter out your fermentation cycle. Your malic acid should be around 0.65% to 0.85%, I wouldn't stress too much about it. Your yeast, while the lalvin71b is good, for apples though I use K1L-1116, it keeps the apple taste better i think.PH though should be 3.5 +/- .3. This can be adjusted with acid blend if necessary. When I make wine and need to make a gravity adjustment, I use corn sugar, it raises the gravity without impacting flavor. For your honey aroma/taste, I would recommend back sweetening.
Cheers!
