Leaves starting to yellow

Hi everyone. My blue mystic autos are 10 weeks from seed and have been largely problem free throughout. Some of the leaves are starting to yellow now. I’m not sure if this is normal at this stage of whether I’m running into nutrient deficiencies. Nivarna say this strain should take 9-11 weeks from seed and I think they are close to harvest (a few brown pistils but trics are still mostly clear) I’m happy to let them do their thing if this is normal but I don’t want to ignore a potential problem. Any advice gratefully received.

Have you been checking your PH? If so is it an issue? If you are close to harvest the leaves around buds will yellow as the buds are taking what nutrients are available. The trichromes should be cloudy or hazy... the more clear they are the speedier your buzz will be....the more milky/amber/cloudy... your buzz will be more mellow....more of a body/and head buzz....Hope this helps....there is a tutorial here on when to harvest... http://www.growweedeasy.com/harvest

Yes it's normal for yellowing, just like old man's hair turning grey. The smoke will be mellow, an smooth ,the whole stalk turned yellow on my last northern lights auto, harvested her on day 89,,, 30-40percent amber, killer smoke. You will sure be glad you waited for her to get done. Nice
Kobayashi.
 
Hi, no Ph issues, I’m not going to harvest until I see a few amber trics, I just want to know if the yellowing is normal at this stage for this strain. I don’t know if anyone has had experience of growing them here. I’ve been going fairy easy with the nutes so I want to make sure I’m not under feeding them at this point.
 
It’s completely normal reaching the end of season. If you are sure there’s only a week of two left then all is good. If you think you still have a month to go then it could be wise to feed a few more times. Either way what we can be sure about is you didn’t over saturated the soil with nutrients and that’s the most common and harmful mistake. It may take longer than you think to fully mature but you’re on the right track doing everything right.
 
Btw I personally think you are at least a month away from harvest so I would feed for another two weeks if it where mine
 
Thanks for your input. A month away would put them at14 weeks from seed, I’ve not heard of anyone growing this strain that has let them go for that long. Most journals I can find online say they’ve been harvested by 80 days at the latest. I’ll wait for the trics to turn amber before I chop them though however long that may be. Do you think I should keep my nutrients at the same levels or increase them slightly? Thanks again, all opinions are very welcome.
 
Yeah I would keep everything as is till final week. Probably will keep yellowing slowly as it finishes. Witch is perfect cause you won’t need to flush much. And yes keep track of the tricomes it just that I’ve had plants looking like that a month away from finishing. Let’s hope I’m wrong man good luck
 
Thanks for your help. I’ll see how it goes time wise. Hopefully not too much longer, I’m itching to smoke it.
 
Hi Kobayashi, looking at your plant close up, I think 9fingerleaves is right, you've got at least a month before those buds are mature. I've still not really caught the auto-bug, I've done 2 plants that didn't really do it for me, meh genetics. But is it important to switch to bloom nutrients for autos as it is for photo plants? Will excess nitrogen inhibit bud growth in autos?
