I was just going to ask this.

Then I found on another site that people do it all the time. They recommend you cut off the top or biggest buds only. And not more than two per plant at a time. More than two and you are risking major stressing of the plant.

I was wondering how to mature the smaller buds, and chopping the top bigger ones seems to be an option.

They also say that early harvesting will not be much less potent than fully mature or aging buds.
