purple leaves and stems

From what I can gather you're still feeding them if you think their nutirent deficient and this far into bud i would be slacking off hard-core and getting ready to flush and let the plants do their thing and deplete the rest of the nutrients from the leaves, which is what they're trying to do, adding food will just prolong the process and run your buds over their prime...Check the trycombs and get ready to.cut and trim

just had a plant do the same its a P/k deficiency. plants tend to show purple veins on stalk and purpling like burns on leaves when P is deficient it also has drying of edges like a K deficiency so i would assume its deficient in both P/k. mine fixed it by adding some Canna pk13/14. Had a look thru your diary that plant started going deficient from week 4 it started yellowing and burning. weeks 3-6 are where it will need the most and is where many think they are over feeding but in reality they are staring them. as sad from what i see i would up my pk boosters a the purpling stalks always indicate a P def unless its genetics,

High, the leaves show a very heavy nutrient burn! In this case I would flush her with pH 6.5 water and a low amount with nutrients EC 1 Here is a link from the grow weed easy website with an article about how to flush: https://www.growweedeasy.com/flushing-sick-cannabis Goodluck and happy holidays!

Do you know of its runoff ec?? If its low then yes more feed, if its high for some reason then it will be a different course of action. Let us know its ec if you can. And we will work from there. Im guessing its low.

Best Of Luck!

The diary linked here (Afghani #1) is not the grow you have a question about, right? The photos you've attached here, for me, say you should be preparing for trim jail.... not feeding her more... Check your trichs, I think she's ready for the chop! Good luck!

they had very nice growth up until week 8 then this happened. i thought its ph issue and gave almost plain water for the last week but it became worse. run off ph is around 7 maybe it just wants more bio bloom🤔
