What is destroying my young plants.
Hi everyone, sorry my first post has to be in the problem section but I need some help / advice.
I have grown some small Echineca plants from seed, most germinated and some are smaller than others, but that is to be expected. However in the last week what were healthy small plants, are starting to be consumed, I say consumed because I don't consider them to be being actually eaten, more melted away. There is only what I can describe as a fur on the new growth that gradually consumes the growth. Hopefully the pics will post and you can see what I mean.....
I thought powdery mildew at first but as you can see no signs on the bigger leaves, any help or advice greatly appreciated. \thx
