I know this is old, but I was wondering about this also
This is totally up to you. If you want an absolutely "correct" reading, then make the adjustment. Some folks consider this very important.
OTOH, if that doesn't matter to you, then don't worry about it.
I don't bother with correction. My hydrometers are calibrated for 60 F and my cellar ranges from 58 F in the winter to 70 F in the summer, so my correction factor ranges from 0.000 to 0.001.
I record the OG and FG to calculate ABV, and since the formulas for ABV are an approximation, I don't get fussed about 100% accuracy. During fermentation I use the SG as a barometer, to know roughly where the wine is in the process. If the OG was 1.090 and is now 1.060, I know the process is about 1/3 of the way through. If the SG is 1.058 or 1.062, it makes no practical difference.
At the end, the FG for most wines will be between 0.990 and 0.996, and it will not change, except if the temperature changes. If the SG is off by the correction factor, it doesn't matter to me.
