Cut Critical Kush and Blueberry 99 this week, harvest pics later. Critical got some mold :-(. That was partially the reason for cutting.
Blue Dream's branches are super heavy, and it's on flush mostly this week
I think this is the most controversial topic around growing cannabis and it is very difficult to find a good side by side comparison online. I plan to do one on my next grow.
At the moment I defoliate. My thought is that it will increase air flow and will direct the plants energy to the appropriate place. I generally do a first defoliation right before flower and then another after 21 days.
Hopefully this helps! Happy Growing!
