Is your light on full?How far away is it?It is the atmosphere as the green leaves are cupping.Turning in.Look at other leaves like mine.Flat and shinny,out flat or tilting up.
@oldskoolkool, thanks for the feedback. found after adding an additional light, it was causing far too much stress. I moved the lights up to 18” and dropped the percentage of output down 20%. I also added recharge to my watering cycle each week. They all bounced back and are healthy as ever.
