I have just entered week 22 on these. They are sour diesel autos. I germinated them April 12. I keep checking the trichomes and a lot seem to be cloudy but still some clear. I haven’t seen an amber one yet. It concerns me because they are going so long. I have been having issues with humidity for a bit. I’m ready for fall weather and lower humidity but I can’t control that. I grow them in an 8x4 tent in my pole barn. I am using (3) 600 watt lights on full spectrum. They haven’t had any nutes in about a month because I assumed I would have harvested by now. It almost looks like the trichomes have just stopped in place. I know the pics aren’t great but it’s best I could do with my phone. Thanks for any suggestion.

CANNOT TELL UNDER THE BURPLE LIGHTS, re post under normal light of flash
I think I see some amber in the last pic… ? Lots of milky. Stigma hairs seems to have all gone orange.
I vote chop. Give em their last watering with some ice, when the pot dries lights out for 2 days, then snip snip.
Congrats! You got a dry room set up?
Yes, in my basement. I have humidity at 55% and temp of 71degrees. Curtain on the window. Should work I think.
Yeah I knew as soon as I posted it. The pics on phone didn’t look as bad as they do posted. I’ll get some more and post them.
Better pic under normal or day light. It’s a sativa so, if you have milky mostly with 5% amber I would go two day dark. I judge 5% by seeing any darkening of triches on upper cola buds. Remember that the triches continue to “age” even in harvest and cure.
Just posted proper pics.

Nothing like Christmas in September! Nice buds… I wouldn’t let her sit under anymore light in a couple days at the most. Mostly milky and it seems some starting to darken. They look like some very tasty morsels. 
Just my opinion, of course. As always the choice of when and how is up to you my friend, happy growing!
Lol. Thanks. I was just sweating it being my first bigger grow. I didn’t want to pull the trigger too quickly and have low thc buds.

I see a lot of milky trikes and brows pistils…thc is high now and SourD is a sativa so it is a good time to harvest. I would go dark for 3 days for the thc to build up, ice water feeding to help…and chop

This was my first year growing Auto’s and we grew 11 plants and 9 different varieties and we are very happy with our results for a first time… We never saw an Auto get amber trichomes and only a couple got to a true milky stage. And I use a pretty good telescope… cheap but works great… I do grow outside so maybe there are differences. We went by looks and time to guess when to pick and it worked great…
I would harvest any that have amber color starting. And also if mostly all milky white should be ready. I cut off a leaf piece to view trichrome on the table for better viewing.
