Ice water shock

So I'm ready to harvest in approximately 8 days and I've seen growers using ice water in the last few days of their flush. I've also heard of washing your harvested cannabis flowers in a citrus acid solution. I don't want to either of those but instead douse them with ice cold distilled water multiple times with a hair sprayer bottle to simulate a cold rain 4 days before harvest(final time I flush) . Has anyone tried this? I'm worried about seeing immediate drooping of fan leaves from the shock.
