My 4 steps defoliation:
* 2 or 3 days before turning into flowering: lollipoping and defoliation from main stem(s).
* ~3 weeks after, when the flowers have started to develop properly: lollipoping and defoliation from secondary stems.
* let the plant recover, then continuous defoliation until harvest: just a few each day, to keep buds compact and help the light reaching lower flowers, but remove only leaves you can clearly see the stalk.
* the day before harvest: keep only sugar leaves, remove all the others. This point depends of how you like to dry your flowers: doing it saves me time at harvest, so I can freeze the flowers as quickly as possible (for fresh frozen bubble hash).
But for now, you should stop defoliation (you have to let the Lady breathe). ^^
