Can anyone identify this leaf issue?

I have two seedlings at day 16. One started getting dark spots in between the veins on the leaves, starting from the tip and moving in. Now the second is starting it. Both have leaves curling up. When it was just the tip i tried cutting it off, since cutting leaves was ok to do with the clones i assumed it was ok for these. Ph is 5.5, ppm around 400 or less, temps cool, humidity low, rez water clear. I had an issue with cloudy water so i cleaned everything and refilled with distilled water instead of tap. I had too many nutes at 800 ppm so i lowered it. Since cleaning and refilling, the bad one has gotten worse and the good one has started to do the same. Internet said mg deficiency or light burn. T5 was 6 inches away but is now 12. Flora trio with about two cups h2o2 is whats in there now. Looks like im gonna lose the bad one can anyone help me save the good one?

1)When it was just the tip i tried cutting it off, =stop mutilating plants
2)since cutting leaves was ok to do = no, its not
3)with the clones i assumed it was ok for these. = no , its not
4) 400 or less, = or less?
5)I had too many nutes at 800 ppm = yep, so early, rushing
6)Flora trio with =troublesome nutrients
7)two cups h2o2 is whats in there now.= ouch
can anyone help me save the good one?== yep here ya go= http://catnews.org/FREE Pot Books/

rosenthal , cervantes set me straight, after the internet killed good buds

good luck

So, youre sayin that you cant identify the problem by the pics? Sry if i sound frustrated, but i dont have time to read a book right now. In hydro this shit happens fast. In the hour it took reading up on leaves and nutrient deficiencies and nutrient lockout, the plant got worse. I have the grow bible and am currently reading it, but being a time sensitive issue, i kinda just need the one answer to the one question.
I just brought the ppm down to 160. Took out most of the water and replaced with plain distilled at 5.3. Water level was lowered in case i was saturating the rw, it was just under the cup but is about 2 inches now. In case ive got lockup and an mg deficiency, i added some florabloom to the foliar spray and wet the leaves. If anyone else has any ideas im all ears. In the meantime ima sit here and read about this stuff until i get a response. Hopefully a seasoned grower sees the pic and immediately knows the problem, wouldnt that be convenient? Lol

stop adding items to your plants! stop foliar, stop changing out water. you have no deficiencies except the ones caused by your overfeeding, over loving.
stop over feeding, relax, keep ppm's low, sit back. there is nothing you can do, nothing you can add except patience to make this better. they'll either survive or they wont. less is always better than more.the damage has been done.

Guess with all that Internet info you missed the one about pH. 5.3 you should see death pretty fast now. Better than letting them suffer I guess.

I knew I'd gotten that number from somewhere. Just looked it up and it says 5.3 for cuttings in the rooter. I just upped it to 5.8.
The other stuff:
As far as cutting the leaves, every single tutorial ive ever seen on taking clones says to cut the leaves in half to slow down photosynthesis. The grow bible said to also do it for mold.
The 2 cups of H2O2 is in 3 1/2 gallons, and i read that it should never exceed 1/5 of the rez water. It also said it breaks down pretty quick into H2O and a freefloating oxygen, so it has to be added daily. That means the 2 cups i put in there for yesterday's rez change should be broken down already.

I also read in many tutorials that you can soak roots in H2O2 to flush them.
Is all of this wrong and H2O2 not actually good for plants?

Ive been maintaining ph 5.5 up until yesterday's rez change. I read that 5.5 - 6 was a good range to combat fungus. Or root rot, one of those two.
Anyway, its gotten worse since starting this thread, so i guess the Black D.O.G. seedlings are done for so these weak-ass bagseed cuttings better root lol

You gotta kill a few to learn.... Here's how they go when it all comes together. The number one thing with growing, don't try too hard. When you start throwing "Stuff" at them when your not sure what's wrong. Nothing will work. Check this out and get back in the game. http://www.ilovegrowingmarijuana.com/hydroponic-growing-schedule/

Save this...

Thanks for that. Image saved and link bookmarked. Is switching to soil an option to save these?
Also its gotten this much worse since yesterday

Dude.... She just ain't going to make it. Drop some seeds or get a Clone. You want to start HEALTHY.

The grow bible and a few other sources suggest nutrient lockup. Mg specifically. Said that until the roots flush and open back up for business, mg in a foliar spray would help. If my only two choices are to watch it die or apply expert advice, im gonna go with apply expert advice. No offense. Even if this first attempt serves as nothing but a learning experience, it's still in my best interest to not give up. The first one is done for, i know, but the second looks saveable. For a poor person workin with few resources, I'm not as quick to throw in the towel, especially when ive got nothin to lose. I just ordered the Heisenberg Tea and some pyrethrum spray for these tiny flies. Fly paper is covered. Not only can i not find a pic of leaves that look like mine for troubleshooting but i also cant find what these bugs are. Some white, some black, both about 2mm.
I have 10 cuttings in the rooter from a bagseed plant but man was i lookin forward to that Black D.O.G. lol at least i found a trustworthy source for ordering seeds, even though It'll be awhile before i can order any more

nutrient lockup? yep, thats what happens when ph, nutrients, etc are whacked. the plant wont up take nutrients even if they are available. Ph must be in range in order for your plant to take up any nutrients. seedling that size wouldnt become mag deficient even growing in a washcloth my man. that size they need very little of your attention. They grow bigger than that in a root cube with water only. you should germinate and vegetate awhile before cooking up with nutrients high ppm maybe?
if it is a lock out, and it may be from your over feeding, there is nothing you can do to fix that except
to stop over feeding. no flushing, no transplants, no hydrogen peroxide, no leaf cutting. Every step you take with an addition
will make the issue worse. no reason to give up if cash/time is not an issue.

tap water, low ppm is your
best chance of a save.

Im gonna keep tryin to save this one. Sittin in ph 6.1 at ppm160, with cool bubbly water, 68° temp, 45% humidity, 2ft T5 20 inches up, and everything else i can think of to make it happy enough to bounce back if possible. Other than the foliar spray twice a day though, and maybe flushing with plain PHed water later this evening, i guess theres mot much else i can do but focus on the clones, but they have everything they need so i dont wanna even look at them until the weekend lol

Thanks man, if i flush later I'll use tap, and definitely nothing else added. Guess we'll see.

twice a day foliar? flushing a seedling? what do you expect to gain with this being done to a sick plant?
nobody foliar feeds 2x a day or flushes seedlings this way...... thats how you know its not necessary, but good luck

Im just goin by the grow books. If the leaves are spotting and curling the way mg deficient plants do, then it sitting in nute water isnt going to do anything. Doing nothing means lettin it sit in the conditions that already proved unworthy. At this point, like i said, i almost have nothin to lose. When everyone says let it die, how can anything i do be worse than giving up?
The foliar part made sense. I mean, to a noob anyway. If the leaves show mg deficient signs, and the roots are locked, what harm is a light mg spray? I know i seem like i cant take advice, but thats only because the only advice is to let it die. I'll stop sprayin and wont flush, but when you said tap water and low ppm is the only option left, i took that as "dump that bucket and refill with plain ph'ed tapwater", so maybe i misunderstood

dump that bucket and fill it with plain tapwater if your tap water is within ph range for cannabis.
deficiency chart=

what you are doing, foliar, ph, flushing, ppm's,etc is not working. To repeat the same results you will have to repeat the same techniques, which you are. If you wish to change up your results you'll have to change up your approach. dont give up of course.
but adding anything to your damaged plant is not helping....but you can clearly see this in the fact that you have no improvements.

you're not growing in the woods, or in a dish rag, you have nutrients available to the plant and all are identified for you.
Your deficiencies are your fault, not because the plant needs more of something but because it needs less. you've burned your plant, it has all of what it needs and then some. you cant flush these out of the plant. it has to metabolize, grow, recover on its own. I give you circumstances that may allow it to do that.....or repeat your current results by repeating your fussing, both will be fun and a telling to you.
if its important to you though I'd get another seed going. f you find it difficult to measure from bottles a bucket of promix with some dry fertilizer (Organicare)might be the ticket. Beware mine is not a "gotta fuss daily" type of grow. its a water and fert only type, per fert directions of course. no guessing here, same results every weekly harvest for almost 8 yrs. no deficiencies, no damaged plants...consider it anyways. I loved on hydro big time, but couldnt do it organically, so I changed up my habits, never looked back
good luck

Update: Affected leaves died off but plants bounced back with fast new growth. FIMed the assymetrical one and mainlined the other. Never flushed, just left them in the quarter strength buckets. Once a day Mg foliar, and added Heisenberg Tea to roots.

Update:
A few days after coming here freakin out, they bounced back and I did that last update. A few days after the tea, they really blew up. Especially the roots on the one growing asymmetrically, which is now doin this thing where it had 4 leaves on the 4th node, i topped, then it grew new tops out fast but the younger leaves are back to 3. So it literally went 3, 4, 3 again. And since when is 4 even a thing? Lol this one has been fun just watchin it do weird shit (4 tip leaves and asymmetry arent even the half of it).

Anyway, for anyone reading who mightve had similar issues, I changed to distilled water, left the lockedup plants in a dilluted solution until i saw new growth (less than a week later), used a weak foliar spray in case the leaves werent gettin food from the roots because of the lockout, and added the Heisenberg Tea, which I'm fkn sold on after seein the difference. They still aren't perfect but I'm glad I never gave up on them
