After some more research I would say this is most likely a Calcium or Magnesium deficiency

I flushed it because some leaves were showing some Nitrogen Toxicity. Run off was coming at 3000ppm and I fixed it to 1500. Now the older fan leaves are yellowing with some brown spots (check the last picture). It's a deficiency? Should I increase nutes? Thank you very much!Week 8

When growing different strains in a RDWC system how do you balance plants with different nutrient needs. My amnesia auto ran into a major cal-mag issue and now is experiencing nitrogen toxicity, while my feminized Jack Herer's are largely unaffected. Thanks for the advice.Week 7

Day 14. Since day 12 a brown spot has appeared on one of the leaves of the first node, spreading little by little. Because of the symptoms, I think it's septoria, so I've sprayed neem oil to see how it works for her. Someone knows what can it be?Week 2
