[Half Bred Smoke]

i planted 2 seeds with long germinated roots. 2 days later i found a big lamp around the house and used it for a light. 3 minutes later my soil or plants started to emitt smoke. so i took off the lamp as fast as i could, and left them in darkness for the rest of the photoperiod(which was only 4 more hours).

i went back to them when the next photoperiod was about to start, and one was dead and yellow. the other had a little yellow on it so i through the dead seedling away, and put the other in the sun and watered it. now a day later it has a grey spot on one of the round leaves and one of thepointed leaves is small and yellow.

i used miracale grow organic potting soil so i dont think its the soil but i dont want my first grow to go completely wrong before one week. what do i do?
