You're over feeding.....seedlings that small need very little nutes.

I seriously have no idea what I’m doing wrong......
lol jk jk jk I heard you the first time and couldn’t help myself lol.
I’m going to take your advicr this time for real and not feed them directly till the Cotyledons start yellowing.

i use greenegenes chart with maybe a lik slower rise in strength. You should be able to look it up online. Just type in jacks 321 feed chart. I think koot med has got a chart too.

Does it matter that the chart is for a reservoir system and not specifics for coco? Does that matter? I checked the jointed chart and I’ll try and follow that schedule, even though it mentioned a reservoir system involved. Also I’ll need to go grab some calimagic as well, I was just under the impression I did it need it at all honestly.

Yep, perfectly legit for hydro, as well as all mediums really (including coco as mentioned earlier). I grow in Sunshine #4 which is a peat-based inert medium (kind of like coco; it's also considered hydro), and I use:

Veg:

3.6 g/gal Jack's 5-12-26
2.4 g/gal Calcium Nitrate (15.5-0-0)
0-5 mL/gal Cal-Mag (depending on what my tap water PPM is)
0.5-1 g/gal Epsom salt (depending on tap water PPM)

In flower, I use pretty much the same measurements for week 1-2.5, then I reduce the Calcium Nitrate by about half, increase the Cal-Mag and introduce Mono Potassium Phosphate (0-52-34) at 1.6 g/gal until end of week six, then I dial that back by 2/3 when week seven starts.

I just started using these nutrients about a month ago, but I have two full perpetual setup environments running, and always have several plants in each growth phase, so I'm dialing in each phase concurrently.

Hey everyone! It’s been almost 10’years since I’ve been on this forum, holy crap! It’s also been about 10 years since I’ve tried to grow anything, at all, period.
so I decided to try and dive into the world of coco Coir as it was told to me ‘ it’s really really easy’ and was recommended to use jacks 321 as it seems simple enough at the same 3-2-1 throughout from seed to clone.
well, embarrassingly I fucked that up somehow and finding coco to be very difficult to get down pat and really need some help figuring this out.

setup is
Coolgrows 3x3x6
190cfm fan / carbon filter
Grow craft 330 w LeD Light system
Canna coco bricks/ royal gold tupur( I killed
My first run through and started my second, ran out of the coco from the bricks and got a bag of tupur to try)
Jacks 321
Starting in solo cups
GH ph up/down.
Ive been running it at 6.0/ piss yellow on the color chart (using drops, phmeter is on the way).
Temps have been 75-80°f and around 55% RH.
I started at under the recommended 515ppms and still have shown signs of nute burn. Even got in contact with jr Peter and there suggestions haven’t really helped. I’m stumped and would like some guidance and help.
I will say also I’m having a hard time dialing in my lights as well Between distance and strength, but I can address they in a different thread of need be.

from this morning. Should be day 14 for the middle one, day 13 for the Left one And 12 for the right. I have photo non fem seeds and have more on the way.

500ppm+ for those is way too much. Even properly rooted 5-7" clones 500ppm+ is pushing it.

With seedlings, I dilute that mixture with water (somewhere between 200-400 PPM) for the first two weeks, then go full strength. For clones, they get full strength as soon as I move them from the cloner to medium.

I store the 5-12-26, Cal-Mag and CalNit mixed in two 15 gallon stock tanks. One for flower, the other for veg. I keep a 15:1 concentrate one gallon jug of MKP separate to avoid precipitation in the tanks. For veg, I just feed away. For flower, I add 250 mL of the MKP concentrate (which is equivalent to a full gallon's worth) to a one gallon transport container, then fill the rest from the flower tank. All plants get their nutrient mix delivered in one gallon distilled water jugs.

To dilute for just a couple of seedlings, I just fill one of the transport jugs half way of the veg mix, and fill the rest with water (the jugs are marked at 1/3, 1/2 and 3/4 increments).

Lights too far away, humidity way too low, VPD fucked. Increase humidity to 70%, keep temps at 80F, reduce feed to 50% strength, water to runoff when you can, don’t let the medium get dry.

Has anyone used this Coconut Advanced Nutrients 5070? Can you leave any feedback?

It seems to me that the reason may be due to inappropriate or poor-quality feeding. It may be that you are doing everything wrong, that is, either you are not feeding enough, or you are overdoing it. As you know, everything needs balance. Try to replace the nutrients that you use for your weed. You can see it here 420growradar.com top dressing for your weed. Here is an overview of the best nutrients from coconut. There are also a couple of useful life hacks and tips for growing weed. From my personal experience, I can say that this requires a lot of time and patience, as well as a tidy sum of money to buy everything you need.
