Don't get lured into the timeframes given in brewing instructions, they are not reliable. Use your hydrometer and be patient. As logan3825 states, 3-4 weeks before even checking it is a good reference. Be sure to use proper sanitation when taking your sample and either toss it or taste it then toss it...drinking it will help you learn the flavors of green beer.
Something is always fermenting....
