Light Stress

Hi there Lysidious, so the good news is your light is not a problem. I see a basically healthy plant with short internodes , meaning the light is the right distance to prevent stretching. This is good. But you’re right to notice the slight discoloration on the newest growth and the burnt tips. These are actually two separate problems. Burnt tips are nutrient burn , probably from slightly too much N. Simply try to reduce your NPk or the kelp based additive which contains N. The discolored new leaves is a symptom of micronutrient deficiency , that’s because it’s an “immobile “ nutrient . Just add calmag and the problem will stop spreading immediately and the plant should recover quickly . Hope this helps ! 🚀
