With coco you just give it water for the last 3 or 4 days and you're good. I'd say wait another week then start your flush and chop her down when you got a day off or something.
Do you have a scope? If not it would be a good thing to get.
The trichromes will not lie. My scope is a 30-60× magnification.
I usually chop when they are all cloudy with 10-15% amber.
I would look daily at the upper sugar leaves. Wait until you see your first amber trich. Start your flush then. Are you planning on a 7 day flush? I have heard people go as little as 4 days in coco. I have been running organics for a while and have not needed to flush in a while. They get straight H2O for the last couple of weeks.
You are looking at the little ball at the top. You will notice in my pic that they are almost all amber. This plant went WAY too long.
You should be using at least a 30× magnifier.
I usually pick a lille sugar leaf off so you don't have to hold it up to the plant.
A camera with a macro setting will get in close enough if you can get it to focus.
