@Zorro123, if these are leaves that are located at the top, the lights may be a bit too close to the plant. But judging by the other photos, that's not the case.
We agree with GrowthConsultant that you might be overfeeding. Try to lower either the amount or frequency of adding nutrients by a tenth to a fifth. Don't be too rigorous by cutting it in half or something. Steer it gently into a better condition.
The rest of the plant looks healthy, albeit a bit yellow, but that might be due to the white balance of the camera. Yellow plants could indicate a desire for more water or nitrogen. Again, don't overdo it all at once.
