WTF is wrong with this plant? 12/12 from seed 4 1/2 weeks old

Do you treat your tap water at all? What is EC coming out? Have you analyzed your water quality report? Does your company use chloramines? If so this is most likely your problem. Chloramine is a hormone disrupter and root destroyer, even at low ppms. It causes strange lockout symtoms and can even cause hermies. Do you let your tap sit out? Does it still smell like a pool afterwards? IMO you cannot trust tap water. The guys that make those reports are pressured into making the numbers appear within EPA standards, but the truth is most tap water is much, much worse on toxic metals and chloramines. Is it Organatek Coco? This coco is very high i calcium and magnesium, unless it is flushed prpoerly. Also, some general stuff with coco:
1 Plain, pH adjusted watrer atleast every other water
2. Must keep it fairly wet- it concentrates nutes really easily causing lockout and other problems.
3. Coco naturally has HIGH potassium keep levels lower then normal (30-50 ppm) unless deficiency noted.
4. Recomended to keep MG kinda low to, 80 PPM max.
6. Flush at least 2X volume of container.
Coco has high Na and Cl ions also, which can be detrimental to the plant.

What I think has happened here is you let coco get too dry concentrating nutes and it has not been flushed properly.
I think you hve LOCKED OUT nitrogen. Any large concentration of magnesium, Sulfer, calcium or iron will lockout nitrogen.

Cocotek is naturally high in MG, SO4, CA.
I Would HIGHLY recommend against adding any more nitrogen, it may excacerbate your problems. Try a FULL four X flush. Wait two-3 days. Plant will still look bad. At that point add a pH adjusted with 60-80 ppm nitrogen and about 100 ppm phosphate.

Also coco has low Iron (1.2). You also seem to have low iron or iron lockout. " factors that interfere with iron absorption of roots: over irrigation, excessive soluble salts, inadequate drainage, pests, high substrate pH," <= all those factors exist in most coco.

WOW......I read your post last night and was way too baked to reply

The only treatment my tap water gets is to sit out for at least 24 hours, I add HESI SuperVit and Epsom Salts........as advised to do so on here by a few UK growers. Once nutes have been added I PH down to between 5.5 and 5.8. I did have about a 2 week period where my old ph pen was acting very twitchy, I would calibrate it, re-test it and the reading would be way off. Think I may have feed at some funky PH levels during this period which is the cause of all my problems....I have now purchased a good PH pen that I calibrate once a day using ph4 and ph7 buffers.

Water quality report below, it doesnt mention Chloramines or Chlorine.........the water never smells of Chlorine/ like a pool even straight out of the tap....pretty sure they add it though.....Chloride is different stuff right? They also add flouride. Water is classed as Hard in my area.

I dont really have any other options than tap water.

The Coco that this plant is in is this stuff http://www.fertilefibre.com/coircocopeat/coir-tile/

Have recently been told that bales are shite and have purchased a bag of Canna Pro + Coco Coir, its buffered......not much help on this plant, but have moved three smaller ones into their final pots using the Canna Coir.

I dont have an EC metre and dont plan on getting one to be honest.

As you say I may have let her dry out too much when she was in her last pot......was told to do this to promote root growth, I never let her dry out completely though.

Ive been watering every other day, should I water every day to keep the Coco nice and moist? Again I was only following advice given on this site......there are so many different people with different methods, I guess its finding one that fits.

Last night I pushed 5 litres of plain water PH'd to 5.6 through her, run-off came out at 6 and was crystal clear. I only had 5 litres sitting out so thats all I could give her, put another 15 litres out last night and she will be getting that this evening. Ill do as you say and leave her a few day before starting up the nutes again......finger crossed she will pick up. If she does survive Im not expecting a great yield but never mind, this is my first grow.

Moving forward I am only going to use the Canna Pro + Coir, give plain water very other feed and not let the coco dry out to much.

Thanks for the input.

Sorry again mate, the mrs was in gettin keyhole yesterday so not been on much as I am now a nurse lol.... Yeah yellow leaves and green veins is iron def, u cant really c that on your pics....

yeah I know bruv, only really shown in the last week and only under the HPS

Hope your mrs is OK.

Yeah just try watering it daily. From what I understand it is fairly hard to overwater with coco, but if you let it dry out, its near impossible to get its original water/air retention back.

Read your water report. You do have quite high chlorine levels, but I'm more concerned with your Arsenic, Sodium, Lead, and condutivity levels. That shit doesn't even seem safe to drink let alone give to plants lol. You have a high water hardness (about 400 ppm). Your sodium is 50 ppm average, sulphate 44 ppm average, and lead is terrible. Sodium and suplhate will displace all sorts of nutes from nitrogen to potassium and lock them out. Anyway, 90% of the time its the water. I think its time to invest in a high quality RO unit with a UV filter my friend, for your safety too lol.

Dnt mean to piss on your parade espoker. But there are a no of different wter quality levels in the uk the best bein in scotland,amd I know plenty of growers who manage fine with "hard water"

@UK - is it the hardwater nutes u have or soft?

Hard water mate

Well if its hardwater nutes and u leave your water sittin for at least 24 hrs a doubt its that. Me personally would put.it dwn to ir medium. A think you'l find it a lot better with the canna,and may a suggest maybe ghe nutes or the canna coco a+b with calmag supplement. Av heard of great results with both

I think the shitty coco bales I used, plus the two weeks with my PH pen freaking out is what caused all of my issues..........going to use up what I have of the HESI nutes and then try the Canna nutes, seen similar results on both.

The THC Bomb has had her flush now, put 25 liters through her over the last two days. She seemed to have perked up slightly yesterday morning, buds are still growing, sugar leaves are still nice and green and are starting to develop trichomes Run-off has dropped down to 6. Will check on her again tonight and will prob start the bloom nutes up tomorrow/ Wednesday......she has around 4/5 weeks of flowering left I think.....wasnt really sure when to start counting

Really? Its that bad?

I hear you on the RO unit but its just not an option for me, financially and where I grow Im already tight on space. Couldn't have a res in there.

Do u think it would b comin out your tap if its that bad? A hardly think the UK government could cover that 1 up lol

That's what I was thinking......and why the fuck ain't I dead after drinking that shit for 32 years lol
