2 weeks before harvest

I'm 2 weeks before my harvest and it's been a year since I did this...

I will be looking for cloudy trichs
I will be flushing just straight water for last 10 days

Am I forgetting someting else? Do I turn off the lights for the last 2 days or something? I can't remember... what am I missing?

There seems to be some disagreement as to whether or not it's good to go with 2-3 days darkness at the end, but the book that I have most definitely says do NOT do this, just keep it at 12-12 until the harvest. Here's a pic of what you're looking for trichome-wise.
