Nitrogen toxicity most certainly will, if it’s severe enough it can and will effect the whole plant, eventually leading it to death if not cured
John coffee, cool user name. Hey, quick question. How many leaves were effected in this way ?
I believe he said they were white widow clones. Well I have grown 5 generation of them
and I have seen this before it turned out it was in the genitics. So no worries

Nice bet your happy today, I’m alright I got the day off work taking a day to be with the family, went to the hospital to further check the rotator cuff and I think I’m gunna have to have surgery to fix it. The first time I tore it they told me get surgery or it won’t be the same well I was talking to you about how I tore it again and this Time is more severe than the first, It swelled all my muscles around the tendons black and blue, and has swelling and bruising all the way into the top 3 ribs and bruised partially over to clavicle closer to the spine…to be honest I think I’ve seen better days lol
