Yeah mines the Same on our wedding cake auto, she's sharing a grow space with a more mature plant so I've had my lights pretty high (80% dimmed) having the same issue, but she's still growing upright, and there's no burning on ours. Maybe raise the light and certainly dim it if you can, unless like us she's sharing grow space then not much you can do apart from try find a balance between the two. She looks good though! If she's still growing upwards don't worry about it, if growth is very slow definitely raise height now. Good luck dude
