You want to flash the plant ? I've been reading about flashing cannabis photoperiodic plants at a certain point of the flowering to create a positiv stress and get a bigger yield.
If you are talking about flushing then : yes you can ! The tricholes ratio is good , I would say 90% cloudy 10% amber so if you are flushing now for a week you'll harvest approx a 80% cloudy 20% amber ratio
