Need help asap, my autos dying fast!

Hi there everyone.
In a bit of a panic, growing some expensive auto seeds, can't really afford to get it wrong at the minute.
They're a little over 3 weeks old now, were looking superb until 2 days ago. Growing in general purpose soil under 24hr 120w LED growlight (as I have no ther option where I live), they've so far been repotted once.
Last night they all suddenly got yellowing on big bottom leaves, I checked the roots on them n they looked like they need repotting badly, figured they were suffering nitrogen deficiency so I repotted straight away, and gave them plenty water, expecting them to pick up over night, but they've rapidly gone downhill in last 24hr, some of top leaves that were looking deep green last night are starting to go yellow. PANICKING!

Any suggestions on what is causing this blight and what to do about it?

Help much appreciated.

Autos do not enjoy transplants so they may get a bit better in the next few days if being root bound was the issue. If being rootbound was not the issue then transplanting just stressed the plants more.
 
would really struggle to get a picture to you sorry. working on getting some PH sticks.

Have never heard about autos not liking transplants, only grown non-auto stuff in the past, always tried to get a big dense root ball by gradually going up in pot sizes. Normally works a treat.
Was looking up all my problems in the plant problems section last night, It seems their symptoms strongly suggest nitrogen starvation which I have put down to not having enough nitrogen due t being rootbound in small pots (the roots came in so quick). They may also be getting too much light, I am growing under 24hr light as I am convinced that certain people unknown to me are able to detect what I am doing by my using a timer plug, (very paranoid here), turned the light off for about 5 hrs overnight, decided that their survival most important thing and a timer may be best what'd'ya think?

Also the soil I'm using is a UK supermarket brand of general purpose soil, and I'd be buying supplements for them here in UK so US brands no good to me. Anyone able to reccommend good nitrogen supplement available in UK or some kind of measurement I can go by to get a one no-one's heard of?
That said they do not appear to be getting worse, leaves are curled down over a little more than I would like but the leaves are not getting more yellow.

Still don't know what to do...
 
I believe the electricity companies can quickly realise that someone is using high power lighting (or at least high power something) twelve hours on twelve hours off, and report this to the police. So I wanted to try n find something that would grow under 24hr light. Not going so well, I'll admit. Looks like I'm going to have to use a timer...
I know what you must think, but my paranoia has kept me safe up to this point.
 
Dude, Do you really think the power companies let alone the Police have time and even more importtantly the money to set up this sort of exhaustive atempt to detect every pot head growing some weed at home. Relax you will be safe.

Yeah it sounds like you've repotted almost three times at this point? That's gonna seriously harm and stunt your plant, if not kill it. But really we need much more information. What nutes are you using if any? Are you over watering? Where's the heat at? Post pictures.

Sounds like some great genetics then, but you should never have to re-pot a plant that many times. Done over a long period of time it can be okay but not all at once like he is describing.

I can't imagine the power company is looking that closely at everybody's bill. If you're paying it on time, they're probably HAPPY about the extra power usage.

I use my timers/lights in off-peak times. The use of high watts during peak usage hours will show on smart meters and maybe raise an eyebrow if it is enough. Time your light cycles so the lights are on at night mostly.

Just turn the lights out yourself you don't have to get a timer. Autos should be grown in 4 or 5 gallon people say three but that's all I've grown besides 1 reg and 2 clones and the rest autos 8 autos and I've had roots out the top with three, to small.. transplanting them stresses them and stunts growth and they can't afford to lose any of there time to recover they need it to finish in the little time they have..
 
In the past repotting numerous times and forming a dense root ball has worked for me. They take in loads more water n when they get bigger they grow really quick and strong.
Anyway, I've never grown autos before, they're behaving very differently.

After hearing that autos don't like transplants I put them straight into the biggest pots they'll ever be in, about 3 hrs ago. 24hrs they had picked up significantly, the leaves were standing flat in the top again like a canopy, but after this latest transplant they are looking a little limp, no discolouration but not as great as this morning. Reckon they're just taking to the new pots?

I'm growing with 120w LED growlight, best thing I've ever used. Fan in it is annoyingly loud but it keeps the cupboard consistently 24c-26c.
There is a chance I have been overwatering, like I said I'm used to their root balls taking in lots more water by this point, haven't given them any water in 24hrs since since transplant to big pots, as they were damp already.

They're feminised seeds by the name of 'think different', high yielding auto decending from AK47, my plan is to turn one of the three I have into a hermy, and have him/her rub the females up til there's seeds and start over. The plants reaching their maximum yielding potential is not my biggest concern this round, I just need to keep them alive, they're rather expensive.

Also, I bought a timer, but still a bit sketched about using it, should I decide to use it what light patterns and timings do people reccommend?
Also I am too sketched to take photos and post them online, sorry guys.
 
By this morning they've all perked up again, leaves standing flat and looking deep gren again, but tips of all the leaves (even the top ones) are yellowing. Only the very very tip of every leaf, never seen it before.
Is this the beginning of nitrogen deficiency or something else?

Update: Just read this has to do with over fertilising, but I'm still growing in general purpose peat-free compost no extra nutes. Very confused.

yeah best thing is to glance in once a day and check they ain't dead, it sounds like nothing's a problem since that was your last transplant

Dude! By coming to this website your ISP now knows you grow pot and they're in cahoots with your electric company to see of any spikes in your electric usage! Garbage men have now been notified to check your trash upon pick-up for anything suspicious in order to hand it over to the authorities. If I were you, I'd pick up and move to another state.

Good luck
