I want to flush for a week or so, how can I tell ahead of time what the plant will look like at the end of the flush? I’d like to get the flush/harvest timing right.
The plant is a Triple OG that was raised from a cutting, grown outdoors in MG potting soil, fed with MG flower food. Currently, it’s got maybe 5% of it’s many pistils looking red and all it’s trichomes look cloudy. Since I’ve never grown this strain (or any others to flowering) before, so I really don’t know what to expect.
Any thoughts?

I only use water the last 3 weeks and then use 5 times water to gallons of soil (2 gallon dirt, then flush with 5 gallons water)
When you flush depends on when your ready to harvest. This is gonna vary for every one and every plant but right after about 30% of the trichomes are amber color, need a magnify glass for this or a really good high zoom camera or camera phone works.
