Emergency Diagnosis!

I have no idea what is going on here, leaves are very crunchy and dying rapidly. It is only affecting 2/5 plants, but both are the same strain (Headband). I'm in 3rd week of veg, plants are in FFOF, and watering with pure RO. The two other strains I'm growing are doing fine.

3.5'x3.5x' tent with lots of ventilation
LEC315 ~20" away from canopy
Started from rooted clones bought from a nursery

Help! It's spreading fast!

Edit: Forgot to mention; sprayed all plants with Mighty Wash last week twice (3-day interval) right before lights off.

Some of the leaves are shiny, but it rubs off. I believe its just residual from the Mighty Wash.

I honest think the Headband clones I was sold has TMV. This looks like the characteristics, especially since its just one of the strains. Do I gotta toss these plants?
 
head band plant pain don't like shit ro water cal-mag feed once a week maybe

Why did you spray mighty wash on your plants is it a P.M thing? You say you sprayed them with lights off? Did this problem start before or after you washed them down? Are you sure they were dry when the lights came back on , because otherwise it looks like your plants were sprayed with a solution that was cold and your lights came on and crisped up things a little. It sort of looks like where water had been sitting and got dried and burnt there.

I believe it started after, but I can't be certain now. I sprayed them because I saw the beginnings of mite damage on one of them. I definitely sprayed them right before lights off, I guess there's a chance the timer malfunctioned. But again, I did the same thing with the other 3 plants and they are fine.

Also, I trimmed some of the leaves yesterday, and there's definitely a lot more damage today. It's spreading :?:
 
There isn't a whole lot of diseases that will do that to your plant overnite. To me it looks like something that was put on the leaves has fucked them up, why not the others? your guess is as good as mine . Maybe those plants were more weak, closer to the lights , closer to a fan ect. However , to me it does not look like its starting from within the plant. Remind me again what T.M V is?? Im horrible with acronyms..

Tobacco Mosaic Virus. Just heard about it today

Ah yes Tobacco Mosaic .... Its nasty on outdoor plants but its not too common in indoor grows in my opinion. I would not be worrying about that if it were my grow but hey everyone has their concerns. Unless your plants came from an area that had T.M.V or you had them outside or they were contaminated from something growing outdoors I think its probably a slim chance. There is Botrytis,Verticillium,fusarium and all sorts of other crap that just decimates outdoor plants. Does it happen indoor ? Yep but its not that likely and unless your sanitation is for crap it probably wont be whats going on. How often have you heard of fireblight indoors?

My idea what that the mother from these two clones was infected (got them at a nursery). I didn't see any damage a few days after spraying the Mighty Wash, so I really doubt that its physical burn.
 
Those are 3 leaf leafs don't worry about them they die off as plant grows the new growth looks good don't over water let dry out and water with the ro and cal-mag lite feed once a week. I'v had clones look real bad turned out to be good smoke
got this clone last week had spider mites look like crap last week WP_000487.jpg pic just now
