Classic volume mistake - need take note of the difference between batch size and boil size.
Just came across this thread and it jumped out at me that the volume must have been wrong. OG is simply measuring the density of the liquid, most of 'extra' density is made up of sugars which get fermented.
Maybe too late now but I would simply top up with sterilised (boiled and allowed to cool) water. It's neither rocket nor an exact science this homebrew.
