Nute Burn or defiency?

Hi! It looks almost exactly the same as my auto ghost cookies, except mine is way way worse atm. It took me a while to MAYBE figure out what's wrong with it and in your case I think it is the same Light burn from too intense lights. You can see that you have the yellowing in the middle where I suppose your led light is and the leafs are starting to turn yellow and show calcium deficiency 'cos calcium is important to process light and the leafs can't just process it all anymore. You have couple options. Either move the light to different position to give the middle part some rest, or you can add CO2 to 1500ppm to help the plant photosynthesize more and this way it can use more light, or you can try to add more nutrients so she can grow in that environment possibly. Either way she i stressed so you should raise the light and give her couple days rest before going full blast again
