If your plants are showing some ammonia burn then I would keep dosing ammonia to only 1 ppm, but I would do this twice a day. This will grow almost the same amount of bacteria as 3 ppm dosed once a day.
These bacteria grow best when ammonia and nitrite are under 5 ppm. If you need to do water changes to keep the nitrite lower, then reducing the amount of ammonia could help that, too.
If your plants are OK with 3 ppm ammonia, then stick with it.
Raising the temperature can help, but only if you can keep the oxygen level up, too. These bacteria need plenty of oxygen. Also, some aquarium plants do not seem to do as well at temperatures in the 80s. I see no problem cycling in the mid to upper 70s if the plants are happier with those temperatures. The tank will cycle with a lower temperature, too, but the bacteria grow a lot slower with significantly lower temperatures.
