If a fish and a half weighs a pound and a half...

Is it possible for my cycle to be done in only 2 weeks? I've brought the ammonia up to 3-4ppm everyday. Each morning, it's back to 0. Nitrites went up to > 1ppm, each morning they are 0.

Nitrates are present.
Temp is 78
PH is 7.4


Seems too quick to be true.
