Tomato seedlings wilting! Please Help!
Two days ago, these tomato seedlings were thriving. Yesterday, I noticed that two of them grew really thin at the base of the stem and flopped over. Today, they all look like they're wilting!
They're all about three weeks old and in a covered nursery with peat. I've been leaving them outside and covered on warm days to get sun for the past week or so and watering when the netting holding the peat turns grey, as per manufacturers instructions.
Can anyone help?
