Leaves look torn

6 week from seed Has been healthy and thriving. 400w MH (18/6) in a 3x3 ebb&flow using AN 3 part. I used Clearex as directed to flush my rockwool, and since doing that I have noticed on this one plant that the upper fan leaves have started to look torn. On looks like someone tore a finger in half. I can not find anything saying what this might be. I can post pics later, but for now, does anyone know what may cause leaves to look torn?

I have the same issue with 2 of my 5 ladies... I have absolutely no idea what it is either. I'll be checking back here to see if anyone has any answers.
