Am I killing my plants ????

Hi ALl
I think I am kiiling these
My Leave seem real drupy I seem to have dots or some kind of pimple's on my steams.
I am using CF lights 6 of them 1400 lumans a piece.
I was watering once a day for the last week I backed off to just once.
I rised the lights this morning 4 inches higher in case I was burning them up.
Any help would be great....
THanks....

I have put a couple of pics I just took Up I have more.
Also One of My Cats....

Are you fertalizing them? if so u may have over fertalized, is there a fan in ur grow room is the grow room too hot that copuld b another reason also over watering could b another reason.
