Neem Oil Problem

I have some Northern Lights and Ultimate Indica clones I sprayed with Neem oil yesterday just trying to prevent any bugs and today all my clones are either very wilted or the leaves are curling really bad I mixed the neem oil as per the manufactures directions and didn't spray in light... What did I do wrong?

They look to young. Lightly spray with water for a few days and see if they perk up. Shouldn't use anything on clones till they're older. I usually wait at least a month before they get anything other than water, a little SuperThrive and a little molasses.

this happened to me twice.
at first i thought it was overfert after a flush problem went away.
everything was fine until i sprayed again for precautionary measures
and the problem came back.

I killed them all they were too young screw up on my part hope somebody else learns from it
