I pulled off a few leaves to take a picture. The newest growth doesnt show these symptoms. I have 6 plants in DWC in seperate buckets not connected. All plants are of the same type but one has brown discolerstion on leaves and spots. 4 of them look perfect. Please help!! I am running jacks at 800ppm since I am 2 weeks into flower and my buckets are dropping the ppm by 200 in 24 hours. I keep bringing them back up. It looks like nutrient burn to me but would I be getting burn while having it suck the nutrients out of the water? Could it be a deficiency?
