Jlk is not a "he," just so you know.
Also, there is not a point to changing the water through your normal fishless cycle. The reason to do a pwc is because the params hurt the fish. No fish = no pwc (unless the cycle stalls, but this one isn't).
Ok, so what are your params right now? And how long since you last dosed ammo?
I disagree that adding ammonia will always give you a nitrite reading. Fish poop all the time, and that always adds ammonia, but that doesn't meant that a cycled tank will always show nitrites when you test it.
I think that continuing to dose once the ammo drops is a good idea, like jlk suggested. Just dose to 1ppm. That will keep all the BB happy and growing. It will also slow down the growth of the colony that feeds on the nitrites if you have fewer nitrites coming in. If you were to just leave it and not dose, that an slow everything down. They will populate because there are nutrients available to do so.
EDIT: That said, there are multiple ways to do a fishless cycle. That is why you are getting multiple opinions. Not all cycles go on the same calendar. The BB will generally do their thing without too much aid, and it honestly sounds like you are off to a good start.
