I’ve noticed on my OG Kush that the leaf tips ha...

Imo, it's defintely nitrogen toxicity. Over-wateting isn'tva clawing exactly.It's More of a puffed out leave like an umbrella. Just too much N in your soil. You can either flush it out, or simply lower your nitrogen input the next week or two. I would just let her use it up until she's at a level it's no longer toxic. It'll fix itself if u let it. Just feed plain water the rest of the week, then decrease what you've been adfing for N in 1/2 or even 1/4. Then work your way back up. I've learned nutrient schedules are sometimes too much. I'll lower it by a couple ml. And work my way up now because my first grows i constantly had N toxicity.

You can neutralize nitrogen in soil by tilling in organic materials that will raise the ph of the soil or hydrated lime.😊 I know im a little late...but for future growing. ✌️

Hello ! Your clawing leaves is a sign of nitrogen toxicity to me and the most effective way to get rid of that toxicity is to flush the medium that will flush the N excess away. However from what I can see on the pictures I would not bet on a high toxicity as your clawing are very very slight so the damages are still reversible. Your leaves looks more like a strain with serrated blades on the edges of your leaves. Now it depends on the nutrients you are using , with mineral nutrients your plant will eat and assimilate faster the nutrients than with organic nutrients and you don't tell us which fertilizer you are using so if it's a mineral feeding then the flush is necessary. I hope it will help you 😁✌️🏼

Howdy @Curtain_Glow you certainly do have the effect known as the "claw" caused by a Nitrogen Toxicity however it does not look to have caused to much damage yet so you caught it in time. This is undeniably a Nitrogen Toxicity and not a PH issue you can tell because N is the only nutrient being effected and its not a root problems because they cause deficiencies not Toxicities. The most cost effective way to get rid of the N toxicity is like you said, flushing with PHed water. However if that is not fast enough for you there are flushing additives that can assist in flushing the plant by breaking down the nutrient salt deposits that are built up. A typical flush will be just fine for you given the light severity of the condition. REMEMBER.. the leaves that are effected by the claw will NOT recover so there is no need to freak out when they symptoms still show on the same leaves. Looking for signs of progression is the only way to tell if you have cured the problem! Hope that helps answer your question Curtain just flush the plants and reduce Nitrogen! Feel free to ask anything you need! 😎

Hi @Curtain_Glow! Indeed, it looks like a slight Nitrogen abuse, not a toxicity yet however, so it's not too late to fix it out and move forward. Flush your medium with plain pH'd water, approx 50% of your container's capacity, then help your medium to dry with a tiny fan blowing a continuous breeze onto your container. Your plants should end their stretch very soon so they're not going to need Nitrogen anymore. Finally, you will need to decrease your relative humidity, as your babies are going to enter the flowering stage very soon, and switch to blooming nutrients. You can also consider decreasing your lamp-to-plant distance, I think your plants are stretching in heights more than they should because of this distance. Hope this will help, keep us up-to-date and happy growing 👊

hey there @curtain_glow : no need to worry about N toxicity, you can tell from the dark green color of the leaves if your over doing it on the N, what i can see is that the color seems fine. I'm also not seeing any drooping, but i am seeing that "clawing" on the side of your leaves. That's could be due to root problems. You're basically doing everything right as far as I can see, so dont blame yourself just yet. Check the bottom and sides of your bags for anything like powdery mildew or anything like mold and other stuff. if you dont see any then it's not a big problem yet. Try adding enzymes or humic + fluvik acid (e.g. CannaBoost from the Canna line), these are so called chelation agents, and they can help fix dead or diseased roots by breaking them down. Then stick to a strict wet dry cycle and the plant should recover. Good luck my friend ! 🚀

Nitrogen will work itself out in stretch. I would prepare for flowering now. Colors seem to be changing so you may not have to worry about nitrogen abundance for long. Otherwise, low humidity can cause clawing. Wind rash also.
