STUNTED SICK DROOPY PURPLE STEMMED SEEDLINGS

[Arthur]

The size issue is more climate induced I believe. Indoor (under LED) 82 to 85 and rH for seedlings is around 70%.
10 degrees and an rH that's off will do just that.
2 weeks indoor and I'm working on a 3rd set of leaves, outdoor temps can drop into the 50s overnight, and the 1 I started same time has just tossed its first real blades.
As to the nutrient issue, it could also be rH related, even tho your mix is weak, the seedling is pulling up more due to low rH.

ITS GETTING WORSE. BROWN SPLOTCH INCREASING. I dont understand whats the issue!

After looking back again through the thread, I believe you issues are from treating coco as soil.
Coco does not "amend" as soil. Coco is a flush and refill medium. You are technically growing hydroponically and need to treat it as such.

I don't know if this one can be saved at this point.

What do you think went wrong here? I followed ask eds coco guide.

 

[Arthur]

I'm not the one to ask, coco was a breeze for me, but I use an odd nute line and run it WAY differently.

Normally if I buy coco, it goes into a 55 gallon can to be flushed really well. Most sources rinse with saltwater, leaving lots of salts behind.
After flushing, the coco is "precharged" with a mild veg nute regiment. From there you ride the pH and ppm.

Slurry test the coco and let us know the pH and the ppm. I have a feeling the cause will present.

7.6 - 8.0 is the ph of the slurry water i strained the water after makiina slurry

There it is. You should be 5.8 to 6.2 and a ppm something like 250.
Your nutrients are carried by the salts they are combined with. Only available from 5.8 to 6.2.
Your locked out.

PH is also like an earthquake Richter scale.
One .1 is a fair jump. 6 to 7 is a monster step.

You could try flushing with pH'd mild mix until you've flushed it down, but honestly at this stage, it might be time to call it and leave it as a learning experience. If she makes it, she's going to be a micro plant at this point.

Well put, I was trying to explain that also but in a much longer and confusing explanation. Lol

I agree with this also. That pH is way off for coco and it will cause lockout. I had deficiencies towards the end of my first grow as I wasn’t watering to enough runoff and ended up with a pH of 7.0 in one of my plants.

When I first start I slurry test my medium, then again when I see flowering signs, and then once more about 4 weeks in. There is always pH drift as the coco breaks down. Always nice to know it's on track, and the ladies are eating what's been given.
I mix equal parts medium (taken an inch or so down) and the plain water I use, let it sit about as long as it would take to see runoff in the pot, gently insert pH meter into and get reading. Ppm meter isn't as breakable.
Am guessing here, but when you checked pH did you use strips? If so, growing in coco will require a pH meter, and a ppm meter.
These are 2 weeks today, in coco/perlite,

The nutrient line I use pushes using a calcium molecule rather than salt, so I run a different ph, but it is just as sensitive to fluctuations. Out of range... my girls let me know fast.
