Good Question! I am getting a lesson in this as well. I have been messing with Autos for three years now and my Mephisto freebie Strawberry Nuggets X Super Orange Haze is a teacher. I have watched this thing slow down ,speed up, stall out. It has been one of my best looking plants too. No defs. I am guessing when I say this but I have about two weeks left. These flowers did not fatten up till 2 weeks ago. or round about there. So when I thought she stopped growing she was growing out in the flower . She was swelling. I have found out that i really don't do calculations based on times from the breeder but what the plant is showing me. We all try to be Mother Nature but none are Mother Nature. We do the best we know how to do . I know I take notes on everything I do in my grows and if I see a problem I check my notes and look for a common denominator
