I would say on you're 5-6th week of using organic's stop feeding them that and change it up to molasses.
If you choose the 5th week, feed your plant only water starting the 4th week, add molasses 5th week untill harvest, this will allow the plant to use up the nutrients already in the soil and while you're feeding her molasses she will be soaking up most of the other nutrients in the soil while getting sweeter and sweeter.
