I can recall a few times in recent years where we got deep into analysis of a problem before discovering a refractometer was used.valid questions although the answer is very simple. I know measuring wine that contains alcohol already with refractometer would not be accurate. I have 4 hydrometers ( they break easily) all glass and never had any problem with accuracy. 0.001, 0.002 would be normal but nothing larger. Ph is measured with calibrated ph meter. I don’t believe in strips.
As I said above, if the SG is 1.030, then most of it is sugar. Adding more is not going to solve the problem. If the pH is +/- 0.4 your reported value of 3.4, you're still fine for fermentation purposes.
Yeast can be finicky -- stir it, airlock it, and ignore it for 1 to 3 months.
