Sounds like you've got the basics of it down, but I asked the same questions and never got an answer that I could work off of. I think that's because nobody can really tell you when it's 10 days or two weeks before it's ready as your setup and this grow are very specific and unique.
Not only that, but trichs are only part of the equation, If you still can't see any amber but the plant is obviously otherwise done (only yellow fan leaves remain, water consumption slowing, etc.) then you pretty much have to take it as is. Alternatively of course you can have a plant that otherwise looks young, but is full of amber and again you've no real choice but to take it as is.
By way of general advice, try to avoid the typical thing us first timers do, harvest too early. Of the three we've harvested so far, two were likely early. All three have gotten us higher than we've been in a long time so it's really not that important to us. We lost some yield, but we have too much anyway.
It takes a harvest to learn how and when to harvest, not sure there's any other way of truly learning.
All of this is just my uneducated opinion based on three months experience, so take it for what it is.
