Sorry Guys, I skipped a few weeks as I was super, super busy.
The Queen turns out to be a monster! Her growth is absolutely stunning and exploded when I decided to repot her into a 18l classic plastic pot. The All-Mix I planted her in again boosted growth.
4 days later I flipped her to 12/12. Pre flowering showed itself approximately 5 days later. Since then she started to stretch and the branches got more firm and woody.
I'm super happy with the ScrOG net in combination with the little LST Clips I bought. I managed to established a pretty even canopy with many many bud sites.
When pre flower started I cut of at least 12 shoots that wouldn't have a chance. I also applied heavy defoliation and lollipopped the lady. Since then she does so well and didn't slow down for a second! :-)
