Around three days ago I bought a thyme plant. It was looking all fresh and healthy. When we got it home, the soil was very dry so we watered it a bit, and made sure there is no excess water in the pot. We put it in a light room, however not in direct sunlight. Three days later (today) it seems as if half of the plant is slowly dying off. We aren't sure what the issue is - whether too much water or too little. Can you please advise what we did wrong and what we can do to save the plant?
