How often are you watering? The soil looks very wet. You should wait to water again until it is very dry (put your fingers into the soil and the top 2-3" dry.) The next time you water, pick up the dry pot first and feel the weight. When it gets to that again, yuo know it needs water. Also, since you are using leds, add Cal/Mag. They require more under LEDs.

Heat stress can contribute to curling. What soil or soiless medium are you using?
