I'm having a similar issue- I brewed this batch Sunday, March 28. It was supposed to be a wit, but I accidentally brought 3lbs of wheat DME and 3 lbs of light DME, so it's a sort of wit. I pitched WLP400. I checked after a week, tons of krausen. I checked last night and I still have a thick, bubbly layer of krausen on top of the brew. I didn't take a hydrometer reading because I figured, "damn. a lot of krausen."
I'm planning to rack to secondary on top of 1lb of Oregon apricot puree. Any thoughts on how to proceed? Ignore the krausen and rack anyway? Wait another week or two?
