Yes it will hurt your plant by black dirt im assuming you mean clay and clay is known for being high in nutrients. Also id add some perlite to your mix for next time. You are probably going to suffer Nute burn on that seedling. However, I dont recommend trying to transplant it that is just going to stress the plant even more. fortunately Ruderalis are very hardy even by weed standards so they could make it. Just be careful watering go too little before you go too much. Miracle grow has nutrients that release as water is poured on them so not only can you overwater them but you can also make the nutrient situation worse. One more thing i would change just personally is the electric cords hanging almost on the bulbs thats asking for a fire.
