@ReservoirDog Hehe, thanks! From what I read, can't remember exactly where, it was suggested to watch the angle of the leaves and basically just put the plants into a drought, but not super heavy is where they were finding results. I think if the leaves are straight out to the side, you want to watch for a 45 degree angle change in the leaves where they just start drooping, but not so much that they are straight down and withering up.
Its been hard to replicate on this last plant, because I only can check them once a day at best most of the time, so I think I kind of overdid it on the first round of drought, showing day 56 to day 63:
In the above you can see the plant ate up the leaves instead of them drooping in late flower. I think this was a bit much as far as droughting goes. The in the final week of flower I droughted again twice. The plant was still using over 2L/water/day so I managed to get two short 3-4 day droughts in before the end. You can see the results and trichome pics in my journal.
I use droughting to not only increase cannabinoid production, but it seems to help the plant finish and use up all the nutrients in the leaves etc.
Here is a pic of week 12 vs week 13 after droughting, you can see the bud shrunk a bit:
