Depends on what medium/soil you're using...if it's something like Fox Farms Ocean Forest or Happy Frog, you shouldn't use anything for the first couple/few weeks because those soils already have a bunch of nutes in the mix, out of the bag.
OF has more than
HF so most would say nothing for the first 3 weeks on that. Once it's time to run nutes you'll use both simultaneously, not one or the other.
EDIT:
I checked the beginning of the thread and see you're running
OF so no nutes for at least the first 2 1/2 weeks or so...
