So I had a weird experience when I was brewing this. On Saturday night after my wort had cooled down to around 70 degrees I pitched my yeast (WLP320). By Thursday morning there was still very little activity. There was a little bit of activity in the airlock but nothing really in terms of a krausen. The first few days I thought it was just slow to form because maybe the CO2 was getting stuck in the fruit layer on top, but by Thursday I figured I had to do something. I ended up getting another tube of yeast (WLP300) and pitched it that night. Since pitching it I've had really constant activity, but the krausen is still only about 2 inches high, I think because of the fruit layer. Anyone else have a similar problem?
