I would wait until you see amber trichomes to begin your flush, until the trichomes mature to amber the trichomes are still maturing and the plant is still growing.

noice. foxtailing is normal, it just means you're leaving them long enough to stack flowers on top of flowers!
every foxtail you see will be new flower with new white pistils. they will continue to do this for a couple weeks. once the "rouge pistil movement" has almost stopped, it's time to check trichs daily and get ready for a harvest.
the better the flush the better the smoke! pure water till the end now?
they may go for 3 more weeks because I don't see many amber pistils. either way starting the "only water" is great now. I wonder if they'll turn purple for you by doing this?
I'm guessing that the blue cheese will be done first.
They look awesome!
I use tap water without any issues, but I'm in soil, not hydro.
Beautiful!
Can you take a couple closeups of the flowers when you get a chance so we can see how much longer? They should be fine for another week or two and should turn purple
Just make sure you harvest your plants before the yellowing reaches the buds, you can watch the sugar leaves as the yellowing progresses. If all the fan leaves yellow the plants will begin using up nutrients in the sugar leaves and then the buds giving a hay or dry grass taste to the cannabis.
