Help - Im about to lose another batch of well rooted clones

[red_eye]

That sucks that its the tent. Is it the pvc in it that causes this?

That shit it toxic!

 

[purpleberry]

I was also thinking it was a tent. I use roots sometimes and I found it to be very light and needs to be feed right when you transplant at 50% or you will get yellowing within a week.

sometimes you got to wait till the new growth. but mag will darken up a bit on the messed up leaves. i stand by my mag def. even if it is Iron the cal-mag will fix it. i just re read that you are using r/o water. and believe this more now. if it is the tent you need to take them out of it right away.

after this problem is fixed. take some cuttings and just give them same nutes and don't use the r/o water and see if you have the same problem. I'm guessing you probably wont. did you chekc the ph and ppms of your run off?

My question is are you growing in a grow tent with white plastic interior? If so my friend you are another victom of the toxic plastic they used to make them.
I would not keep adding stuff to them like people are saying. Just water till things get better.

hmmmmmm interesting theory. Ive lined my rooms and or built rooms using panda for a long long time as have several friends and we have never had a problem with out gassing. That said, plastics are nasty nasty stuff that can cause all sorts of genetic issues in human embryo development, MAY be causing the increase in homosexuality and gender issues (im not a homophobe and dont GAF how anyone gets their love its none of my business, just stating research), lead to deafness, blindness, cancers and myriad other issues....just never seen it do what you are saying. Interesting though.

this link will lead you to thousands of peer reviewd research papers on bp-a, dioxins and other chemicals found in plastics. select a triangle then select a paper to read, mostly from pub-med.



sorry for the hijak...


I think you have yourself a classic case of micro nutrient deficiency.

I bet it is the tent if he is using one with white plastic insides. I went thru it. Went crazy for a few weeks myself till I found it was the tent being toxic.
If you do not believe me and want to keep adding stuff to make it worse go ahead.
That is no way in hell a Mg defficicincy. If it was a Mg dif than you would notice it a while ago making the outer leaves dark and the insides of the leaves a lighter color.
Try moving a few of your plants away from that toxic thing there growing in right away and see how they bounce back in a few weeks. I would move all of them myself and burn the tent and poles. Otherwise you might as well get out the shovel and start planning a funeral for your plants. Also dont forget the asprin for your headache.
Really not trying to be rude but it straight looks like toxicity coming from something.

if he has them in a tent like you say then it probaly is the tent. when i 1st baught my tents about 2 eyars ago they were talking about this problem at the hydro store, but it has since been fixed. i even said in my last post if they are in a tent like that to get them out right away. no one is doubting you smokey.

if it is not the tent then Cal-mag will fix this issue

Chlorine toxicity for sure....either from the tent (poly vinyl chloride) or your water if you're close to a chlorine dosing station.

Leadsled - Flushing was done to the last batch that died off. It was a 3x volume of water per container.

I have a 3' tall tower style oscillating fan constantly blowing a on them on a low setting.

They pass the hand test, there is no discomfort or excessive heat at new growth level.

When I got these clones from a local coop they were under low wattage flouro lights. I dont think there was more than 50 watts on them at the time.

From what i have seen of bleaching, I dont think thats what this is. What i suspect is that the plants are nutrient starved due to the sudden increase in their metabolic rate from the jump from 50w flouro to 600w hps.

I just watered them all with a 50% veg nute solution (6.5ph, 550 ppm going in). Runoff was 6.2ph 1500ppm.

Ill update a little later tonight with new pictures and hopefully signs of improvement.

I surprised no one or yourself is bothered by a 1500 ppm reading with clones. JK
Especially with 550 ppm going in.

Wow, that EC is toxic for cuts.

Good point JK.

I think i have 2 posts waiting to be approved now...

Thanks again for pointing me in the right direction guys

Im convinced that this is chlorine toxicity due to the PVC. After seeing the pic at the link below and doing a bit of research, I know we had a match. No other images of deficiencies or toxicities matches quite like this does:



For those of you just jumping in - this is my second batch of very well rooted clones (2nd transplant). I had the exact same symptoms on the previous batch, except last time was hydro in coco. The plants never recovered, went completely yellow and I scrapped them. This grow is in soil.

My first grow was in a home built box, and completely successful.

Ive since pulled the tent off the frame and put it in another room... maybe i can talk them into honoring the recall...

So now the million dollar question is do I scrap them and start with new clones or hope they recover?

 

[leadsled]

get em out of the tent!!!

damn I am idiot. I should have asked if you were in tent. I knew something looked seemed familiar.

Yo edux10, The pics of the plant look familiar!! Like one of the ones I killed. That pics almost make me snap thinking back when that was happening to me.

I pulled my hair out for almost a month on that few years back. Hydro store owner kept claiming the tent was fine. (it was his used tent)

I almost snapped. I killed so many clones and previously never had that problem.

That was such a nightmare. I took em out of the tent and they thrived like no tomorrow.

Sound like something else may be going on too 1500ppm runoff?

Most important no tent.

 

[Smokey503ski]

Toss the poles also. I have read that some company's were claiming it was from the toxicity in the PVC in the poles and some manufactures say its the white plastic they used to make them.
I have never had a problem with Panda film either. Was not claiming that to be a problem. But am glad someone pointed out the hermes with using the Panda. My guess to that is they have a light leak somewhere.

 

[DeviousSB]

Leadsled - Did you have clones recover from the toxic tent? Im trying to decide if these clones will recover and how long I should give them to show improvement before tossing em and starting over.

Im going to let them recover before attempting to troubleshoot the nutrient concentration. Last thing I want to do is shock them with a flush when they're on the rebound from the PVC. Im using straight roots organic soil, which shouldn't be too hot for very well rooted clones.

My poles are steel - but will still be temporary. Im ordering a Secret Jardin dr120 tomorrow. It sure will be nice to go back to non-headache gardening.

 

[Jalisco Kid]

That problem was 2 years ago, I would think if that was one of those tents it would have gassed off by now. But do try this experiment. Once you set up your tent, make sure you feed your clones 1500 or you will have failed the experiment. JK

Yes, the clones recovered.

I made some jokes how the hut would make a nice body bag for the prick that sold it to me. Then was able to get my $$ back and return the kevorkian death tent.

Shop sold it to some other unfortunate soul.

How cold is it getting during lights out?

JK is one the mark with the ppm. You have a problem there. Maybe you are flushing out soil sediment?

Not light burn btw imo. Never grown in a tent so don't know much about the gasssing, only know of it.

It looks like a super severe Fe lockout or yo' ladies are going through a pretty drastic temp swing between lights on and lights out. But maybe I am a stoner and missed somewhere you are on 24/0.

 

[DeviousSB]

Temps for lights on/off are 82/72 - Well within acceptable ranges IMO.

lights are 18/6

The runoff tested was only the second time ive watered the 1gal pots. Im sure the 1500 is skewed in the high direction from both soil sediment and the 2" of hydroton in the bottom of the pots (unwashed). Ive used this soil straight before and have never had problems with toxicity or burning.

Ive read multiple times and from multiple sources that roots organic soil runs light on the nutes, so im just not that worried about it. Even though i have all of the synthetic nutes at my disposal im trying to keep this grow as organic as possible. Conditions permitting, ill be using very little in the way of nutes before i transplant into 5 gallon containers full of subcools super soil mix.

I bought a Growlab 120 this afternoon and have since set it up. Very happy with my purchase and would highly recommend it to anyone looking for a tent. Not as light proof as the secret jardin but its got some nice features.

 

[caliogk]

I rocked a top feed hydro system (12 ladies, 1 1K under an adjust a wing) in a DR120 and got 2+ elbows :harvest:

The awesome thing about the tents is there is reflective material around the entire crop, light is definitely maximized in those things.

 

[DeviousSB]

Cali - Did you run A/C with the 1k?

With the 600 in this thing im more in the 83/84 range when the lights are on.

 

[caliogk]

I didn't and should have towards the end.

It was feb/mar when I started so it started to get hot towards the end.

A sealed aircooled light with ac will be very proper for that tent :rock

Keep learning and never give up!
