I brewed this in extract form a few months ago, using the WLP001 and a 2l starter. I oxygenated with an aquarium pump/hepa filter. With in hours I had fermentation, and had to use a blow off tube (it was a very active fermentation). After about 48 hours fermentation slowed quite a bit, and was steady for a few days. I left it in primary 3 weeks. OG 1.060/FG 1.012/Ferm Temp 68deg
I'd say leave it be and let the yeasties do their thing. Maybe take a hydrometer reading every few days to see where its at. Personally, I pitch the yeast, put it in the ferm chamber and forget about it for a few weeks.
