For blueberry auto grow, 9 weeks since sprout, my pistils have started to turn brown, about 10%. Putting on my 25x goggles, all tricomes are clear. Do I wait until tricomes change color or clip when the pistils are +/- 90%. Or will everything suddenly come together?
There are growers who struggle to get amber trichomes like @Not2SureYet, based on his setup. I don’t look at them any more; rather look at the aspect of the plant to see if it’s mature. The concern with an early harvest is a loss of bulk during the final couple of weeks.
Welcome to the forum. I have to agree with @Dclark Even super quick ones I have seen average 10 weeks from seed. It doesn’t mean there are none out there. I just haven’t seen them. I do mostly autos. Do you have any idea about what week of flower you might be in. I would guess you are still at least 3 weeks from harvest. maybe 4. I see most BB autos show a 8 week flower time advertised. Once you see cloudy trichomes. You will probably be about 2 - 3 weeks or so to finish
