First, a question, the trichome pics are from the bud, and not sugar leaves, correct? Want to make sure you look at the trichomes from the bud, not the leaves.
If it were me personally, I would harvest in a week or so, but I don’t like a lot of CBN (ambers).
In reality, when to harvest is a personal preference, and you should look at this photo as a guide.
Clear trichomes look like glass, cloudy trichomes look like plastic, and ambers look amber in color.
Also, the trichomes will continue to develop over time even after harvest. In my personal experiment I observed 5 days of trichome development going from clear to cloudy. Though I did not test further than that.
The other fellas have got you covered on the mildew 
I’m no pro though
