Yes, they were pretty healthy seedlings in the beginning
The company basically answered their soil isn't meant for peppers. The packaging lables it as a container potting mix for all kinds of plants, including vegetables

Luckily I'm not too crazy about peppers... If this happened to my tomatoes, this would be different. Can't wait for the first seedlings to show up
