More than likely, I'll say I didn't and I just need to be more patient.

The only time you'll get stuff coming out of the blow off tube is when the krausen gets big enough, of course. This usually means a VERY active fermentation and/or wheat in the grist. As long as you keep fermentation temps under control, I wouldn't expect a blow off from a nut brown ale. I've never had a blow off, even with some pretty high pitching rates.
