Nuked nutes, in this case too much N (give your babies a flush to help this), humidity looks a bit high (try to keep it between 30-70%, 50-60% being ideal), over/under watered (as your humidity's high seems as if your girls might be over watered) I think the humidity is also causing your plants to get light burn which is causing them to look disformed and nibbled at, this is just my 2cents. Hope your girls get back too good health! Keep us posted, Cornish
