I'd give it 2 weeks minimum. Depends too at what temp you're doing it at. I did this in the summer I believe, so it was around 20ish in the basement, so pretty quick. I'm now doing S05 at 16 or 17F on the main level, and it's taking more time. I'd give it 3 weeks in the primary just in case.
In the meantime, if you're looking for something quick that you can drink ASAP now that you have your grain order, you could try the same recipe with SO4. It will take more like 8-10 days. I just kegged a similar recipe with SO4 and it turned out much sweeter/frutier I found. Different, but still very good.
