ha ha I'm in california...I wouldnt put a plant out until May.....Is colorado warmer than the foothills around Tahoe?

It depends on your lighting.....if your plant is outside and there is more than 15 hours of light in a day (some people say 16, some say 14) it will keep vegging. If there are LESS light hours the plant will flower. It doesnt matter how many weeks its been in veg or inside or outside or whatever.....the only thing that matters to the plant is how much light it is getting daily. If you keep changing it around.....18/6 then less, then more,, it may very well hermie due to stress.
