Your rez temp is a bit high. By the look of that leaf, looks like you had some nutrient solution on it and it got burned.
 
i agree with moonraver looks like you dripped some nutrient solution on it by the burn pattern
 
looks good. its not a problem. however, you do have some leaves curling upwards, you probably need to up your nutes
