  3. I suspect heat stress yet I'm still new to this. I've moved my light to 20 inches from top of plants, I added a portable ac as a temporary cooling solution.

  4. everything else sounds fine probably just the heat/light bleaching combined with mag def...you can foliar feed them some epsom salt or even a mild complete nute to help green them back up but those white and real yellow leaves might be toast...also have some over watering which can lockout nutes...are the roots pretty established? hard to have lack of oxygen to roots with rdwc but the creases in the leaves show over water
     
  5. Oxygen de saturation in water due to heat possibly? I'll grab some Epsom salt and try it. Thanks for the suggestions.
