Leaf problems

So i checked if my PH pen is still accurate, and it was 0.5 points higher then it should be, so when it showed a PH of 6.5 it was actually 6.0 I selected the answer from Ctrellis90, because it was a deficiency, but that's because a salt buildup caused by too low PH. I recalibrated the PH pen and now i only give her water with a PH of 6.5 and no nutrients because i think that there is still alot in the soil, it looks like the problem is not getting worse anymore. Thanks for all the replies! I hope others can do something with this information, and remember to recalibrate your PH pen every month or so!!

Water to at least some runoff & check your pH is within good levels. It could be a build up of salts , stopping your plant absorbing the nutrients. Goodluck

I would check the runoff ph and ppms. Make sure your not deficient or have a toxicity. 200ppms or more LESS then your input and your deficient, 300ppms or more MORE then your input and your leading to a lockout. Try to get ph near as 6.0 as possible. I would increase fertigation and lower feeding for a day or two. Check runoffs and see what it tells you. Due to the age it could be the stain as I've read it's very meticulous to grow. Could be the pheno and its fading off earlier then expected. Goodluck and please consider selecting me as the answer so I can be entered for a chance to win grower of the month contest 🙏 please and thank you 😊

as you are this far in your grow, i would not do changes, you may have had some issues or more than one , its just to get the balance in the grow yellowing wilting leaves are normal in an aging grow. as long as your leaves are still there and alive, i wont pull them to early, because they are the motor of the plant, they fall down by its own when they are sucked out greetings

I think your run off is not sufficient. Causing assorted other issues.

So, your buds are on a wild journey, but you've got these rebel leaves going yellow with burnt tips, right? No stress, just dial down the nutrient rock concert a bit. Ease up on the Powder Feeding power and let them chill. Check the pH vibes too—aim for that sweet spot around 6.0. Your strain's a tough cookie, but even warriors need a balanced groove. If the issues persist, a detox flush might be the encore your plants need. Keep it cool, and let those buds rock on! 🌿🎸
