I brewed up a Kolsh style beer last Friday and I am not sure it fully fermented or might just need more time.

I did a partial mash with

2.2kg of pilsner malt

500g of Munich malt

2lbs of dry pilsner extract

2 oz Hallurtau

2 packs of Lellemand Koln yeast.

OG was 1.042

Fermented at 64F and after 3 days the airlock activity all but stopped so I moved the fermenter upstairs where it has been at 68F since.

Checked the gravity yesterday and it was only at 1.020.

Just wondering if the fermentation is stuck or just needs more time.

Thanks in advance.
