Hi
My first post...I have my plants in a hydro operation. I am getting a brown blight looking problem on the lower to middle older leafs. PH is 5.8 to 6.0 Using bloom and micro @ 1100PPM. Also there are some plants of a diff strain showing zero sign of the same problem in the exact same system?? Any help is appreciated. Thanks

Thanks...I am at 1100ppm I always thought 1600 and under was safe?? Could the other strain handle nutes better? Does it work that way? Thanks again

all strains are different. Some can handle the full dosage of nutes while others it is a good idea to cut the dose in half.
