kinda hard to tell from the pics but it looks like some kinda mold...do you have lots of fresh air circulating? during my first grow i had simlar probs and it was due to not enough fresh air....
Did you make those clones yourself or buy them? Are you sure the "stuff" is growing? Sometimes, when I get a little sloppy with the rooting hormone powder, the clones come out looking like that.
Dont know if it was the same stuff but that first pic came down with a bad case of powdery mildew all over the clone so I chucked it thanks anyway guys
