She is showing dark, clawing, papery leaves. No spots yet. In Veg. nutrients have been; cal+mag & a little bit of K. Wondering about heat stress, PH or overwatering. Haven’t added any nitrogen that I’m aware of. Any ideas? I’m a noob. Thanks!!

Hi @earlsmeds! Well, I see dark leaves + clawling upper leaves + yellow tips ==> these are symptoms of a Nitrogen toxicity in the past weeks. What medium are you using? What's the NPK ratio of this substrate? Your soil might have been too rich for the young plant you had. Now as an emergency move, I'd try to flush her for 3-5 days with plain pH'd water and see how it goes, this is not too serious at this stage so she should be fine and recover quickly. Hope this will help, keep us up-to-date and happy growing 👊

Hi earlymeds. The leaves of the plant are quite darkgreen, and you say they are clawing, these are sings of nitrogen toxicity. This is known. but here comes the news.... most calmag Products content Nitrogen. and a lot of it. Giving you girl so early nitrogen poisoned her.I dont know which soil u use, but there are nutrients inside too. It all added up . I let you link to a helping site where you can diagnose and help by yourself, because only you know what your girl got on nutrients soil, water etc. https://www.growweedeasy.com/nitrogen-toxicity-cannabis. For a quick stop of your problems give her fresh soil and she will feel better soon. The hole effects of the excess you see days to weeks later.Like dude said, reduce your nutrients of do a break for recover. Happy growing

Hey man, i checked out your pics, to be honest i don't see any clawing which is a good thing. What i do see is some pre flowering, which means your girls are ready to be flipped. My advice is don't panic. When you panic you make mistakes, so chill - you're doing great. PH is spot on, you're clearly very conscious of this. A tiny bit of nute burn, but really don't change anything, it just means nutes are available and your plants will be ready to stretch real nice. Keep up the good work Earl ! Good luck ! 💪

Clawing is usually an indication of wind burn. Do you have a fan blowing on the plant? If so, you may want to back down the speed or put it on a timer to give the plant a break from the fan periodically throughout the day. I also see what looks like a slight nutrient burn on some of the leaf tips. I'd recommend backing down on your nutrients to 1/2 or 3/4 strength. Nutrient manufactures recommendations should be considered maximum levels, most of the time using less is better for the plant. And you also only need to feed nutrients once per week, not with every watering. Hope this helps. Good luck! 👍
