PLEASE HELP! My leaves are hanging downward...
As I stated, pH and oxygen levels, primarily oxygen. You're recirculating the reservoir but you're not doing enough to oxygenate it. Now the roots are being flooded with oxygen-poor water, and with poor oxygen also comes poorly-maintained pH. Fix oxygen issue (add an airstone to the bottom of that whole mass and hook it up to an air pump, or run the water through a home-built oxygenation reservoir before recirculating it back to the plant,) then adjust your pH, as adding oxygen will make it swing.
