So it just so happens that I had to leave my plants unattended for about three days. During those three days the power went out at my apartment and so they were without light (they're about 3 weeks old) or water. When I came back, the leaves are extremely droopy, and some were really dry. I wanted to know if there is ever a chance that they can get back to being healthy through regular watering and lighting (they were very healthy three days before) or should I just assume that they will die. Please let me know ASAP
