I need a sanity check; my hydrometer reads 1.004 in water, should I be using 0.004 or -0.004 as the offset? I've always used -0.004 to subtract back to 0.000 but my numbers seem low...
Yeah, distilled water at ~68F, though our tap water here doesn't have much in it so it also reads 1.004. Thanks for the confirmation
