Well, can't see trichomes so all I can go by is just what I can see, I see quite a few white hairs.
Going only by what little I can see, I'd say at least a week maybe longer.
Then again, sometimes things change quickly.
Your best bet is to get somehow to magnify the trichomes and check them daily and figure out what you want from the plant.
Speedy high harvest just when they're starting to get cloudy.
Bit more mellow, harvest when just a few start to turn amber.
More of a couch lock sleepytime high then wait for about 30% amber.
But the only way to really ascertain the exact time of harvest that you're looking for is going to have to be up to you.
You need to be able to take in the whole plant and look close at several areas and you really need to be standing there to see and feel what the plant is telling you.
