Go buy a scope of at least 30x they make small cheap ones for about 10-15$. You want min of 30x.Problem is that it's a little hard to tell a white microscopic dot from a clear one, even with a jewelers loop... Amber seems a safe bet, but by then you are too late to really flush.
I read an article though that said resin production was similar to a volcano that when it flowed fast it was clear and as it slowed it turned to milky and then 'hardend' into amber. It also said that resin production can ramp up and down over the flowering cycle, making cloudy but not milky trics and then back to clear, so looking for amber is one of the more sure fire ways of telling ripeness.
Guess i'll have to dig up the article if I"m going to reference it, it was either in HT or Skunk.
I always harvest at differant times,I cut some when the trics start to get milky,then I cut some that are 80% milky and 20% amber
Time to harvest = when it's ripe.
Indicators
