[Reefer Rick]

This is a clone from,i believe to be a skunk strain .I have kush clones as well.They all have had the same conditions but this girl an her twins have been showing these sign on the leaves since vegging under a 400 mh. they otherwise seem healthy.
I've looked around and seems it could be several things .
I need to pinpiont this to get rid of this before it gets worse.
Any input appreciated

I have been feeding very lightly and no foliar feeding.I have two strains in the same room and only this strain is showing these signs.
