@stan_mephisto would you be happy to answer a growers questions?
I grow in coco and airpots and top and heavily train my girls. I never let them get above the rim of the airpot (till about day 45-50) once I have 30+ heads and the pot fully covered - similar to SCROG.
It seems as the girls show sex at the same time, but then, only when I choose to “release” them will they enter flower.
I have Sour Livers running to mid 50s before preflower, same as Sour Crack and HBBS. The down side is they run to 110+ days but yield heavy.
I release the girls when I have 30 plus bud sites and the pot filled with primary, secondary and tertiary canopy at the same height.
Here is a top down view of a girl at day 49. I just keep training out using pipe cleaners! She becomes self supporting. However, requires a lot of defoliation keep everything in check!

I am starting to think flower is triggered based of where the plant thinks it is. I.e around the 3-4th node.
Thus far in growing Meph girls for over two years, it seems effective if you chase yield.
I drain to waste and flood my girls with auto irrigation.

Thanks for any insight you can provide to what triggers the auto flower response.
