Magnesium deficiency? Potassium? Phosphorus? I really can’t tell. Strain is super silver haze in coco, using blue planet nutrients. I thought it may have been nitrogen but I added more nutes and it has gotten worse since yesterdays feeding
Are you referring to that one yellow edge on that one leaf? Is it happening across the plant?Here's what magnesium deficiency looks like: https://www.mrgrowit.com/single-post/2017/11/14/Magnesium-Deficiency-in-Cannabis-Plants
Yes i’m referring to the yellowing leaf. i thought it could be overwatering also but I am 100% sure my plants are being under fed. They are at about 625 ppm but my tap is 200 ppm.
