help my clones are dying

I have had 4 clones doing rly well for the past month. I hadn't had the money for a second timer, when my other broke so I had them siting in with momma @ 18/6. I had them on that light cycle for like a month... I know I was broke ok. Well I put them in a 12/12 less then 8 days ago and now they look a total mess. The first signs where a blackish spots forming on the leaves then curling and then they just look completly burnt. But there not I have burnt plants befor with light and nutes so I know its not that. But if anyone can tell me wtf to do to fix it or save them id rly apprecate it. I mean the only thing I can think of is the light cycle change freaked them out? Cus I water them the same, and I haven't changed there pots in over 3 weeks. But if any one knows or has had this problem plz tell me what I did wrong and how to fix it.
Quick summary:
Its a soil grow, 4 pots med size, I have been using my ott lights on a 24/24 untill my timer broke, they where cut from a 4 month old plant, spent 2 weeks under my bed in a jiffypuck dome, then went into my grow room on a 18/6 cycle for a month. and 8 days ago i started them on a 12/12 when i got another timer... thats when the problems started.
*edited this i had mixed up the time of my cycles when i was writing this sorry i was high lols

Pictures speak a thousand words.

Betcha a dollar it's overwatering, though.

right after cutting
a month after clone
and this is what the worst one looks like now. keep in mind this has only started to happen in the last 8 days... the leaves are brittle but dont fall off and there not burnt, i mean i have burnt other plants they turn brown and light yellow or even in some cases a white color but anyway. the light is no higer or lower then it was last week there is a good 7 to 8 inch gap inbetween the light and the top of the plant and there is a fan on them aswell so its not heat. so i hope that if one pic is worth a thousand words that 9 pics can save my plants.

switching to 18/6 in the middle of flower is a bad, bad idea... they flowered for a month and they're still that size? if you switch back to 12/12 now it could take weeks for them to recover... even then you've delayed flowering possibly to a standstill... IMHO... these clones are a waste of time right now if you try to heal them. in the time that takes, you could start a fresh batch and yield more than the measly 1-2 grams you'll get off those clones... my tips for next time are to water less, by only watering when the pot is light rather than a "schedule", and to respect the photoperiod... you can't expect this plant to survive, with a small rootsystem, switching from flower to veg. your pics = testimony to that fact.

Should never switch from 12 12 to anything
Ore then 12 hr light, like the other guy said, it could take weeks to recover, good luck

Wrong answer.... as far as your "should never switch"... People sex plants and revert them to veg all the time. Yes they will take a couple of weeks to revert. Switching light cycles didn't do these guys in, his lights did. You notice he said they were with the mother at 12/12? #1) what is a mother doing at 12/12 and what type of light? When he went to 16/8, what type of light? Those plants look like they have heat stroke now from being way to close to the light source. He says they are about 7" from light, but what type of light? He insists the plants are not burnt but what does the pictures show? A dry burnt plant.

Look at the soil, see any amendments like perlite? Nope, just an organic seed starter soil, with nearly zero nutrients. That soil sucks for retaining water for a bigger plant. The leaves were not able to pull enough moisture from the roots to keep them cool. There is no way that the entire plant failed like that, new growth and old, from a deficiency. A deficiency of shade maybe...

Post above says it all. Heat stroke.

Picture #8 does too. I can see the moisture gleaming on the surface.

It's overwatering--you owe me a dollar

Your plant is starving in a sea of plenty.

I saw the misting too. That even makes the respiration rate of the leaves worse. crispy dry leaves result. Instead of all the misting, I'd have raised the lights.

And let that pot lighten up a WHOLE WHOLE lot. Way too much h20 in the medium. It looks like it's as heavy as a cinder block rt now.

man thats not from switching the light hours thats straight over fertilization..god daaammmnnnn..my advice to u is READ READ READ and remember what u read and google is your best friend she'll tell u erything

in all the pictures the soil looks soaking wet..so im thinking over fert or to much water...when u plant in soil u drown that bitch almost, water till u get a good amount of run off..then u let it dry out completely to get your roots looking for water (grow) and then your water every 2-4 days or so depending on pot size

dam that is some bullshit

hey umm i rly dont think its over watering i just read all the posts and one guy was saying the lights are to close one guy said its to much fert when i am using none and you thins its over watering. i have them in lil med size pots with a resavour on the bottom i mist them 2 times a day and put less then a dixy cup of water in the top when the res is empty the pics where taken right after i had misted them so they look rly wet. but i think the problem was hit on target by the one guy i had them in the room with the mom she has 4 2500 cfls on her and they where just on the floor by her and then i put them under there own rooting lights which are ott lights here is there page http://www.ottlite.com/p-266-plant-growth-task-lamp-bundle-reg-13596-sale-8999.aspx
and the shock just freaked them out cus they where not use to it. that would be my guess. but i am still not sure.

and why the fuck does all my posts have that fucking add in them thats bullshit

I don't know, man, maybe I am not following your problem, or follow what you did to those suckers.

You are trying to revert a few itty bitty clones back to veg, right? And they were under 12/12 light for a month and stayed that size, right?

Judging by that, something is effed up to begin with, and you should probably either consider starting completely over, or be prepared to sit this one out-- becuase it's gonna take a week or two, maybe three, before things will start looking right.

They're all effed up anyway, so maybe your best bet would be to repot them in a mix that has perlite or anything else that'll promote good drainage. In other words, you can add a gallon of water to it, and can dry up completely in less than 4-5 days. Because the way they are right now-- deadsville.

nope u following me right but i mean i thought i was doing everything right from the first pic to the other 4 i saw alot of improvment but then it went all down hill..
so is there any way to still clone off the mom since she is well into flowering? i mean i took the cuttings off the bottom branches of her befor she had buds everywhere.

And what is the reservoir for? Are these pots sitting in standing water?

not rly i dont fill it up like its supose to be its like where the run off would go if u where to flush it, the water might sit for a day or less because i am not rly using that much u know how big a dixy cup is right? u know them lil paper cups u use at the dentist and shit lol i mean i could go get a measureing cup hold on, not even a 1/3 of a cup like every 2 days or so.

Ok, All.

First of all, your soil shouldn't look that wet after adding a dixie cup of water. That soil mix is waaaay to rigid, too dense, for MJ.

You need to become friends with perlite, brah. The next ten bucks you spend on that grow? Perlite. The chunkier, the better. It'll turn any store brand soil to gold.

Mix one part perlite to one part soil, for starters. A fifty/fifty mix, and move those half dead midget teenagers into the new mix. Water to your heart's content. (not literally)

And yes, you can still take clones off a budding plant. Take some cuttings off the lower branches- the ones with airbuds on them.

They will look funny for a while. All those little pistils will turn into funky looking, gnarled leaves. Kinda neat. It'll take about three weeks for it to resemble a healthy and vegging plant. Depending of course, you follow my advice about lightening up your soil mix by a LOT, for starters...

ok, ill go out and get some of the perlite, but other then that is there anything i should do now to fix these or should i just start all over the one in the pic is the worse of the 4, but i mean the stalks are still a dark green color and junk. i rly would like to do all i could to save them should i just leave them sit for acouple days and see what happens? stop watering and just mist them? or what?
