Nice presentation - good info. Big help here! Found issue, N toxicity, leave tips curling down. Have hydro set up, dble. bucket system, 1 plant in one bucket, other bucket dual reservoir ( 6 gal.). Nutrient feeds have been at 1/3 of listed amounts on bottles to avoid burning plant. Turned out reservoir level got too low and this must have concentrated the nutrient strength. Following up with adding straight distilled water. Live and learn. Thanks for your help LM!
