Hi! Bought a Fittonia a month ago and was doing really well up until yesterday when she started getting saggy. I've watered it and this morning i found it even worse. I've moved it next to a window, because i've thought that there wasn't enough light, because we had a few cloudy days, but it didn't help. The soil was really wet so i've put the pot on some paper towels to absorb the excess moisture. Should i do anything else? Will she recover?
