How much longer ?

2 or 4 weeks to go ? Do I start flushing now ?
60 percent orange pistols lots of amber on the sugar loafs . Week 9

Once your pistils have oranged and then fully receded into the buds it's time to start monitoring trichs.(on buds not sugar leaf)

You don't need to flush, its a myth.

as above, but can you post some close ups of that lovely plant so we can give you an opinion on its state of readyness please

Looking like a month to go.

Flush the idea of flushing, down the toilet
