WTF is going on with these leaves???

It's been going on for a couple weeks. At first I thought it was heat burn, so i raised the light up, but now it's appearing on all the newer growth as well.
I'm using FFOF with 20% perlite and some dolomite lime. With the last watering I gave them the first dose of nutes consisting of 1/4 strength FF and 1 tbs of molasses and 1 tbs of liquid karma. The girl is 12/12 fs and about 2 weeks into flower but seems to be off to a slow start.

did you check for bugs?

Yeah, I don't SEE anything, but never bothered to check with a scope.

I don't know, could it be nute burn?

I don't think it's nute burn, it was doing it before I gave them the first dose of FF. Last time I grew this strain, it was serious dank. I want to get it back on track asap. I'm going to take a gander under a few leaves with a 60x scope tomorrow when the lights are back on. See if I see any critters.

your lights too low maybe? check your PH?

are you using RO water?

I run a 250 hps with a cooltube and its about 12" above the girl. She should be fine as far as heat goes. No ro water. I'm using tap water PHed to 6.8

Its all small brown spots.

To much chlorine in your water?

calcium deficiency or spider mite

Will Epsom work for calcium? Or just mag?

just magnesium you will need to buy something like this

well go get scope and look under and all over leaves and do u let tap water sit out to get rid of clorine? usually 24 hrs

thats cool least your girls might feel a bit cooler and happier.
im stumped i can only think of cal def if its not mites. seems his lamps 12inches above the plants so burn seems unlikely
