Just add the ammonia, test for ppm, if it's not at 5ppm add some more.......it's not critical. You just need a 5ppm each time you test. When your nitrites start to come up keep adding ammonia to feed them. If you keep track of how much ammonia it took to get your 5ppm, when the nitrites start to come up real well, cut back on the ammonia to about 1/2. You just need enough ammonia to keep the cycle going.

PS You can really cut down on the cycle time if you add a handful or more of substrate and some filter media from a cycled tankl.
