My sweet little OG

I am sad to say that my sweet little OG did not make it. She is back with Mother Earth. I think I made the soil 'too hot' when I pre-fertilized with the bio-fish. Her first true leaves turned yellow, and then everything degraded from there. Maybe nutrient lock out?? I will try again and keep the seedling in the small planting cup for an extra week next time; and significantly reduce the fertilizer. This will be the last post
