Severe Nute Burn

Originally this was a grow w/ a journal. But considering the events about to be explained, it will now be an example.

Nutrient burn!

If you haven't heard of it get a ppm meter.
If you have heard of it and experienced it prepare to cringe!
If you have heard of it but have only seen examples of curling tips than this is for you.

I'd like to start off by saying I do know how to grow! I swear!
On Christmas I propagated 18 seedlings! 14 made it past sprouting and 9 made it to the 2nd set of true leaves.

All was well in my grow, a little under watering at first and overwatering. (Never used fabric pots before)
On 01/12/2018 I foliar fed using the wrong mix. Instead of a comfortable 200 I used 800ppm.
This just murdered them overnight.
The healthy to deathly photos are just overnight.
They were placed in what I like to call my "ICU Tub" in hopes to control pH and ppm for recovery.

Labels or careful measurements can be there difference between a bountiful harvest and a waste of time.

And this examples show how dangerous it can be ever time we pamper our girls. It looks like you have a set up to be proud of @ShedsAndTents . You'll be back in the race shortly Thanks for sharing.

yeah holy shit they got decimated! I like your idea to have an ICU though. Fucking Trapper John couldn't save 'em though. Do you think it would have made any difference if you had sprayed at night and maybe washed them off before light? I sprayed plants once for mites with Dr Earth garlic rosemary oil under light and they immediately got yellow spots everywhere the spray hit. I'm not sure if I should try foliar feeding.

I have recovered plants as bad if not worse than those they are still small. Flush them for a day then light nutes give them a week and see.

Can you take a pic of the roots?

I think we all had one that won't die lol...takes long time to recover

lol It is called weed for a reason

I really wish I had taken a picture of the shamefully embarrassing results of my first attempt at hand watering Coco.... I had the the illusion of everything going great for 5+ weeks of VEG, until one day, the lime green shoots appeared....The progression was frightening, within a few days it was a hideous, twisted, and shriveled mess...
It was eventually euthanized.
The image of the that bush will haunt me forever...

Too much care is definitely possible!
Avoiding intoxication in the grow room helps too haha.
I am so at fault...

I appreciate the optimism and share of experiences! I have the plants on a 19/5 (was 20/4 slowly moving down) and the schedule is staggered to coincide with the hottest part of the day being lights off (about 11am to 4pm right now) so my availability to the plants during on and off times is low so I have to foliar feed about 5 hours before lights off so it was probably dying right after I left... Ugh...

However! After a day or so in the ICU three plants displayed root growth so I planted them in small containers. One of them (also had the smallest root mass and was least sprayed) seemed to be just thriving. So he was left alone in the ICU to hopefully be a silver lining. These are not my cash crops I know but I have love for them, so I will try.
After they showed green growth I just defoliated everything that appeared useless. Interestingly enough the survivors were also the most internodal progressed. Those with no lateral growth died immediately.

In order the pictures are;
Small pots transplanted to.


New growth in soil transplants


New growth in Dwc guy



And the photos of the roots as requested
Note, the characteristics of the roots during ground zero aren't shown, but 2 days ago the roots were lacking micro roots and they were browning. Starting from the plant down. The reservoir was actually lowered yesterday because the roots have grown from a single strand touching the reservoir to what you see.

Hey no worries it happens to all of us. I don't want to say it, but it is possible that you need to consider pulling that one. I know you love her already and she holds a piece of your heart, but in reality she May be more prone to bring a disease and pest into your grow room. It can hurt I know I am the king of burning my plants and from my past experience of trying to save my babies they gave me PM, and id like to some thrips and mites on them but they may have came regardless. I think whatever you choose to do you will grow. but some tips I use to prevent burn is never underestimate Humidity also. It has made some of the worst burn cases ive been through (letting it get to low, scared of mold). Also I didn't view your journal but it appears your roots are receiving a lot of light? Roots hate light.

Thanks man it takes balls to post the ugly
But this should help ...someone...
Thanks

Very true @Cold$moke

That is some crazy work there! Just curious what did you feed them and how much of it did they get to get them to do that?

Anyone remember the movie Dc cab? There is a part in the movie where a preacher and a someone else was talking and the dude said to the preacher " REVEREND! You got the balls the size of church bells"! I was about 13 when that movie came out and that quote has stuck with me since! You sir have the balls the size of church bells! Good to see that they are making a recovery though. I bet that was one hell of a learning experience.

@Fertile Mind does have a good point! Roots do not like light.

But more importantly! You are giving the water light too and that can potentially fuck things up real bad and real quick, it's ALGAE! That's the first that comes to my mind.

I am no pro but just my 2 cents.

I was hoping to scare people into being careful. Scareful? Maybe.

Either way I do believe I am getting too much light into the reservoir but the light shown in the photo is much more for the photo's sake. I have a white plastic bag surrounding the tub, I am going to put a black one underneath it until I can spray paint it black. It was a cheap 30$ Dwc on Amazon but with an extra air pump and some TLC I think it will be where my seedlings start. Fits under the t5 nicely and roots seem to explode, even after injury. I have had issues overwatering seedlings in the past which have may lead to other issues resulting in low survival rate and bypassing watering is helpful to me, for that reason. It may have even been low DO saturation because I used to believe warmer water was best for watering.

Either way!
They have survived to say the least, and until they show signs of a worsening condition I will torture them with being alive :c

As for what they were fed it may also be part of the issue.

I mixed a full strength solution of GMB, b-52, voodoo juice, rhino skin and calmag. Calmag was definitely over kill as I learned afterwards calmag is for deficiencies not to replace ppm of tap water. Rhino skin is also advised to not foliar feed. The mix came out to 1700ppm in a gallon. Diluted to 200ppm for foliar and 800ppm for soil feed.

Edit:

I have two spray bottles. One had the soil feed to moisten seedlings gently.... Getting a label maker.
