NB Palinian stuck?

[pcsol]

Hey all,
I brewed my second extract Plinian six days ago (the first batch was superb)and as expected the fermentation took off like a rocket and required a large blow off tube. However the difference this time from the first is that after just three days it went from peak activity to nothing. I switched over to a conventional fermentation lock and there's just nothing happening. My first time around with this kit last fall it was active for at least ten days.
OG came in on the money at 1.070 and now sits at 1.012. Ferm temps are consistent at 66 -67 f.
Wyeast 1056 1000ml starters pitched @ or around 70f for both as well.
I'm a bit baffled and wondering, could this thing be done already or has it hit a wall ?!!
Thoughts?
Thanks!

Air lock activity doesn't matter... @ 1.012 down from 1.070, it's probably done.

Obviously leave it alone for another week or so, but that's not out of the ordinary. Mine usually hit FG around 4 days at the most lately.

Thanks Psylocide.

I was contemplating a re pitch but I think you're right. This brew has quite a dry hop schedule so I I'll be sitting on it for a while. I'll follow up with FG and end results.
Thanks!

1.012 is great attenuation. I bet it's done.

Just thought I would follow this post up with a closing.
The Plinian was transferred and dry hopped as directed,final gravity prior to bottling stayed at 1.012.
Bottle aged for three plus weeks, and other than a LOT of bottle sediment the brew is perfect and just as good if not better then my first run with this kit!
thanks for the helpful reply's!

Moral of this story; Don't get jumpy, be patient, relax and have a home brew ;-)
