I know it can't be heat stress. I ruled that out. I'm using a tube Fluro and have an ac in my room. I'm using organic mg for soil with NPk at 10 5 5 mixed it with seedling soil because my seedling soil was to light every watering it would push the seedling down to the point of no return but I also used this for all my other seedlings and no burn any ideas
