Suddenly all goes a stop

So I made a nice brown with some of that oat malt and 2lb of honey this weekend. All went great hit all my numbers and a 83% efficiency as usual aerated the wort with O2 and pitched a decanted 1800ml starter using WLP060.
Next morning it was rocking pretty good but now 2 days later all sign of fermentation has stopped???

I have no idea why this has happened, the temp is 68-69F all conditions should just be right for it. Anyone has anything similar happen to them?

Check your specific gravity it may be done.

I've had beers ferment out that fast. It may very well be done with a starter that big. Of course, it could be stuck, only your hydrometer knows for sure.

It may seemed like it stopped, but it is still working. Let the yeast do some cleaning up after themselves for a few days before racking.

Just because you're not seeing airlock activity doesn't mean those little yeasty buggers aren't still doing their work.

What does the hydro tell you?

It tells you the specific gravity. If that doesn't change, then the fermenting is done.

I think his question was to the OP, meaning has he gotten a consistent FG.
