I count from the day I start 12/12......and the tips are rounded because of a technique i use...I pinch the tips of most of my buds....just like an 1/8 off a tip.....I have done side by side comparisons.......and the ones I pinch are not only fatter they also weigh more than those I do not pinch.....it's a type stress training ...and I have been doing it for about a year now and am happy with the results.....I remember the the rk having more rounded single nugs ....I see whiteberry was dominant.....the only rk traits I see is the huge fan leaves and trichome production....rk was definitely more bushy.....
