Sorry, but your readings do not make sense to me to be honest, if ammonia is being consumed by bacteria then these bacterias should be giving out nitrite, your readings say zero nitrite.
At the very least you should have 2.77ppm nitrite if 1ppm ammonia has been absorbed by ammonia bacteria and converted to nitrite.
(nitrite bacteria take longer to colonize so you may not see any result for nitrate yet)
Am not sure why you are getting these readings, think you mentioned you using API liquid test kit, are these tests being carried out following the instructions using clean vials and lids, not using you finger or thumb over the end of the vial without a cap whilst shaking the vial, and waiting at least 5 minutes before reading the result?
Human error is a major factor in inaccurate readings, this happened to me on several occassions when I first started the hobby to be honest and I shortly afterwards learned what I did wrong, I was not cleaning out the test vials properly as well as the sample of water must be taken from at least 3 inches below the surface of the tank water. The surface of tank water may contain scum or floating particles that may interfere with test results.
These tests MUST be followed correctly for them to have any value in accuracy.
And lastly, am not sure why you added ammonia when the readings showed 1ppm ammonia......
Quoted from the fishless cycle article, have highlighted in red the part that should be followed during the early stage of cycling:
"If at any time after the first ammonia addition (Dose #1) you test and ammonia is under .75 ppm and nitrite is clearly over 2 ppm, it is time to add more ammonia (Dose #2). Add the same full amount as you did the first time. Now, begin to test the ammonia and nitrite levels every other day. (You should be seeing nitrate soon if you have the kit.)"
Taking from that, you should be dosing the second dose when the ammonia is below 0.75ppm and the nitrite showing at least 2ppm.
Please follow thie article as best as you can, diverting from the advice of that article could possibly lead to a cycling crash or stall and would have to restart the process all over again.
