Question about planted aquarium and fishless cycling

Thor,

I need your input. This morning approxametley 8 hours after the last ammonia add (up to 2ppm) the ammonia level had only dropped to 1 and the nitrite jumped way up to 5. This evening, 19 hours after adding ammonia findings were pH- 8, NH3- 0, NO2- 2, & NO3- 80.
Can I keep adding a little ammonia dailey and wait to do a water exchange this weekend? Or would I be better off doing one now? Then after water exchange, if still adding ammonia and I check the leveles another time or two and find the ammonia and nitrite are both 0 with nitrate 40 or less I should be able to add fish, right?
