Chopping early for butter?

I have a girl that has been flowering for about 2 months now. About a month ago I let it nearly completely dry out causing it to eventually lose all fan leaves and hasn't shown much growth since. I have to other girls that have been flowering just as long and their buds are twice as big. I would like to chop to make more room and give more light to my other girls since im only workin with 400watts. Can good butter come from premature buds? Im wondering how the high will be, all the nugs are frosty but far from amber.
