I am noticing some yellowing from the middle of leaves going outward. I picked them off of my plants but can anyone tell me what this might be? I thought cal mag but I gave more a got a few more yellow leaves. Plants look fine aside from the yellowing of some leaves

Also seems a little early for liquid blue, I can't get to my chart right now but I don't think blue starts till around wk4 of flower. I'll double check that in the morning. I seen you said you can't get a run off ppm but could you get a run off pH?
Looks to me like you have a pH issue causing multiple deficiencies issues. Are you in soil or Coco?
What are you growing in , how often you water
I wish we were able to diagnose just by looking at it but most of the time more information is needed. What nutrients have you given the plant and how often? Are you in soil or coco? What is the pH and PPM of the runoff?
