When do you guys start your pre-harvest flush? Do you flush when all trichomes are milky, milky with some amber, etc.? I know I can change the type of high based on when I actually chop the plant but wasn't sure when to do the actual flush since there is a 2 week lead time. Here is what the plant I'm looking at harvest first looked like as of yesterday (sorry for the crappy pic I had to use my phone to take a picture of the microscope).

I flush/leach when most of the trichomes are cloudy. From the looks of your plant, it looks like it still has quite a ways to go. You can also get a general idea when most of the pistils on the plant have turned from white to brown.
It was a small piece I cut off the bud. I can try to get some better pics later today. The Trichomes from what I'm seeing are clear and cloudy. Definitely not all cloudy at this point. This one is on day 54 (it's an auto).
They look clear to me and is that on a leaf? If so you want to look at the buds. What week you in?
