Thanks for the feedback and how bizarre that my initial message has disappeared!
The photo below show the 6 black velvet petunia plugs I planted in these 2 identical pots which contain the same compost. The pot on the left contains the plugs which appear to be dying (black leaves!). The pot on the right seems unaffected.
Both pots have been in the greenhouse for most of the two weeks since I planted them.
Below is a close up of the affected plugs.
Any idea why this is happening and if there is some way of me saving them?
