Hi Megans-mum,
White fur on the top of compost would suggest to me that the compost is too wet and too warm. Throw it away!!!!!!! The seeds will have rotted anyway.
Heated propagators are difficult to use I find. Getting the heat and moisture right needs practise. I just use a warm environment in the house in spring and after that I sow in the plot and it seems to work. I have been gardening for years and like you in the beginning I lost loads of plants by too much TLC. Grow them hard and you will have much better plants and crops.
