I'm not sure what it is you're worried about... if it's the fact that the buds are not standing up straight, yeah your lights are too close... pull them up another 4-5" ... If it's the color, it looks like you had given the plant too much nitrogen earlier and may still be in a lockout situation. If you have those worries, flush her with 3x the pot volume of pH'd plain water - for you, that would be 42L ... let her dry out before giving her anything more... at that point, you can resume your nutes.
Good luck...
