overfeeding might cause ph to drop in your pot.I don't think it is a deficiency.You have nutrient burn,meaning excess nutrients in your media.as you keep feeding lots, ph drops more and more,plant starting to show signs like this.check your soil/coco ph,also your runoff ph.I think it has problems there.I would do this and keep growing.sugar leaves still living.give it one more chance if you ask me

I think also a potassium defiency. Best course of action is to do a full flush and then apk boost in your next feed. As your still at least 2 or 3 weeks away from harvest bro! 👍🌱

I'm with Denzel on this and it looks like a K deficiency which is usually coupled with a Cal/Mag deficiency, as well. At this point in the game, though, I would certainly leave them be. If you're chopping in a week and you're in flush cycle, adding nutrients may not be the best course of action. This is a naturally occurring problem too, and even though this is a little advanced I seriously wouldn't worry about it. To avoid next grow I would simply keep all your notes on your feeding schedules and see where there may be a lack of P/K supplementation or where your Nitrogen supplementation may have been too high. Rule of thumb for next blooming cycle would be to back to seriously up your P/K/Cal and Magnesium supplementation. That's what the girl is really looking for a this stage in the game and she looks like she didn't get enough. She got what she needed...just not necessarily what she 'wanted'. You didn't do anything wrong at all, just needs a tweak in your next run. Your buds are good! You're at the end game and you almost have some fine smoke to partake in. Don't worry about these deficiencies, you made it! Flush her, chop her and enjoy. If this was at all useful and you have more questions I might be able to help you with, drop me a line in PM and we can talk further. Cheers and happy grows! Nothing to lose sleep over!😃👍

Chances are your correct about potassium deficiency. Could also be magnesium deficiency. Either of this issues are common late into flower as the plant is beginning to divert attention away from maintaining flowers as it knows its life cycle is winding down. If your planning to flush soon it may not be worth worrying to much. Fan leaves develop deficicenis and die off late into flower. Hope this was somewhat helpful. Best of luck
