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?
Thanks in advance - shift8=*
Bro no way it’s done at 9 weeks from sprout.
Thanks, btw my grow room is in the higher temp range, going between 78 and 85 deg. Plants are green and healthy.
Wait for the trichomes - harvest based on them not "hairs"
Most go by trichomes.
One of my first attempts was blueberry auto. Days to maturity was 88, 102 and 108.
How about pictures in white light?
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.
I’m charging my camera, it will be a while, pictures to follow.
The first plant to pop has the biggest buds and had some issue, but I fixed it. The other 4 are green and healthy.
it is pix 2 with big bud - sorry
They all had same soil, water lights, nutes so all I can figure is genes
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
