basically my 1st ever attempt here, meant to be 9/10 week sour diesel, Dwc, 250w hps dual spectrum in a 3 ft by 3 ft tent, currently 2 day away from week 9 but week 2 is when flowers showed 1st sign, currently running 1.7 ec, roughly 0.2 of overdrive and 0.8 of ec is sensi bloom a +b, on ec ph 6.0, basically it's yellow leaves on upper leaves of about 3 colas/main stems, any tips? I'm looking to harvest week 10 ish, with flushing last 7 days as its Dwc, any help appreciated

Completely normal..you're less than 2 weeks from the finish, fan leaves start yellowing like that as she gets to the end of her life.

Likely iron deficiency. Sulfur and iron both. Don't sweat it at this stage.

Iron? Sulfur? Wtf? How do you come up with something like that? lol..the yellowing is on a few random big fan leaves in the middle of the plant..both sulfur and iron deficiencies happen to the very top first!!!
He's in week 9 he said? 10 week strain..you do know that plants don't stay 100% green until harvest right? lol

He said yellow on the upper leaves and cola. That's how. I'm aware of phosphorus and potassium deficiency signs. I'm going by what he says. Interior Alaska with zip bandwidth for large pic viewing

I actually based it on the pics..rather than what he said lol. not sure still how one can come to a conclusion of iron and sulfur deficiency..especially now that you claim you didnt even see the pics! lol Because he said 'yellowing near the top and upper colas'? Why cant that, in theory, be a lack of manganese, or zinc, or too much p or k..they all cause yellowing near the top! So does heat or excess light..to pick out two elements and say it's likely that..and you admit not even looking at the pics? why throw blind advice at someone who really is looking for help?

Yellowing at the tops is indicative of sulfur and or iron. Period.

Oh my...that proved your knowledge right ther..now i understand your reply lol. just so you know...any and all immobile nute deficiencies will start at the top...or an excess of a cation like p or k..will hurt calcium, copper, zinc, manganese as well..so no..yellowing at the top of the plant, is not exclusive to a lack of iron and/or sulfur! lol Either way..he's on the last week of the plants life..its not a deficiency of any element!

Dang, wasn't expecting it to get so heated, but yeah i know it's getting the end and this is common it was just how it was like 2 of the 5 main colas got the yellowing of leaf, starting green and yellow to yellow, mid and top, on one, but as is showed no signs of flower till week 2 I was under impression she could take an extra week, and if so the yellowing is a n issue, noobie so not so expertise do on the subject, hence the reason of this post

One week before harvest! Yellowing why? because it's missing food? No! It's natural..grow a few plants..you will see it's all normal..don't follow crazy advice that will have you dumping in food at the end because they tell you the plant is hungry lol.
