Northern lights are turning yellow

Hi my friend. more experienced friends will comment. but I want to give a few ideas. I've made mistakes before. as if there was more than one problem. I think it burns the nutrient surplus. upper leaves appear yellow, lower leaves greener. Could the light be too close to the plants? I guess it is necessary to keep the light away for a while in stressful plants. Also, leaves hanging for weeks appear to be a major problem: excessive watering, pH imbalance, etc. It can happen. what kind of soil do you use. I think you did a good job. You are definitely much better than me :)) don't let negativity get you down. you will do great work when you overcome these problems. Best regards, good luck my friend.
