I'm going to agree with the already made statements about it still being too young and to not try back sweetening it yet. If it's not fermented out to the yeast's tolerance level (ABV) then adding sugar will probably just kick off more fermentation, or more active fermentation.
I have two traditional meads in process still. They were started on November 24th, 2010... They're still dropping in the SG area. Getting damned close to the posted limit of EC-1118 (17.9% last time I checked), but could go a bit higher (ABV)... I plan to let them bulk/batch age for at least another couple of months. I used 12# of honey in the 3 gallon batch, and 20# in the 5 gallon batch.
That being said I also have a blackberry melomel started at the same time (was one busy day)... That's another 3 gallon batch, using D47 yeast. I used 8# honey, 3# fresh blackberries in primary, then added 4.5# (total) post primary (7.5# of berries total). Color is EXCELLENT, but it needs to mellow some (close to 14% ABV)... It was HOT in December/January, but has been mellowing since.
I plan on letting all three batches age until at least May/June as they are now. At that point, I plan on racking to corny kegs, getting them to seal, and let them age through the summer time (in a cool area)... Come fall, I plan to bring them back up to regular temps for a month, or so, and then bottle. I will check on them from time to time and release any pressure in the kegs.
I hope that the melomel is closer to being ready in a few more months, but I'm prepared for it to need until the fall before being ready (or later even)... I also plan to NOT stabilize these batches. So, the mead will need to finish as it will. I had planned the traditional batches with a bit of residual sweetness in mind, which I'm almost at. Probably closer to 1.020 now, if not lower...
