    I thought it might be light burn because I'm using a pretty high powered led. The light is within the recommended ranges too. It may also be too little cal mag or too much oh fluctuations. What do you think?

  5. I would flush and add fresh nutes with some cal mag maybe even foliar spray with some Epsom salt
  6. Unless you are organic then just add some cal mag earth juice makes a cal mag that is just cal mag no added nutes like nitro
  7. I have a cal mag supplement and I added that. I also raised the light a lil. I'll check the ph when I get home. I just calibrated my ph pen and set all my bucket reservoirs to 5.9 ish which is what I always aim for with ph. Maybe lowering to that ph messed it up. Does anyone know more about ph fluctuation causing leaf deformity.
