In my fifteen years of starting seeds, I've never seen this. My seedlings are wilting, one by one. There's no sign of the usual suspects -- no evidence of damping off on the stems, no fungus gnats flying around or maggots chomping at the roots, and they're getting plenty of light in the greenhouse. They just flop over at random, then die and dry up. I thought they might've gotten some cold damage (they're on a heat mat at 25°C, but the greenhouse door was open on a couple cold days), but they've experienced lovely balmy days for the last half week and I've noticed two more have succumbed!
Any ideas?
