get yourself at least a 60X magnifier. 100X would be even better. Watch the trichromes, look for mostly cloudy. I had an og from reserva privada going 84 days & not ready. Same with a Trainwreck & a Dutch Passion Blueberry. Everything about the buds said we are ready but the trichs don't lie or so I have been led to believe. I can say this , upon testing a few small buds 10 days apart the difference was amazing.
