I started these (see pix) from seed, transplanted them into peat pots a few weeks ago, and have been taking them outside for fresh air and sun during the day. The second leaves on about half my plants started getting papery brown spots, with a few of them beginning to wither. Does this look like overwatering? Underwatering? Temperature stress from the ups and downs? A few nights, I left them on the porch after sunset and it got into the low fifties. The house is usually around 68 degrees. Thanks so much! I hope it\'s not a fungus or something.
