give it a few more days to reach its fg. If i was you just reseal the fermenter, leave it for at least 24 more days. Dont mess with it anymore. Within a few days it will reach FG, but the yeast still have so much more to do. THey will clean up the byproducts of fermentation and give you a better cleaner tasting beer. Then when they are done, they will fall to the bottom and make a nice compact trub giving you a clearer beer.
When i stopped fussing with my beers, and let them finish on their own I started getting some better tasting brews.
As Revvy would say "Yeast have their own agenda, they dont follow ours" Give them plenty of time to do their job and you will be rewarded with a gold standard beer.
