I have 5 harvests under my belt and have never had this problem. They grow fine in the peat pellets then once I transfer them to a pot in coco coir the plants stop growing but the roots keep growing. Can't afford for this to happen as I rely on these harvests to pay my bills so any help is greatly appreciated. They've been seedlings for a whole week now and not growing nodes.

Roots have to establish in new pots before foliage expands
More light means more vegetative growth as well

I know that but I'm trying to figure out why the growth is stunting in the seedling stage of the grow. I have one set of true leaves for one week now. At this rate it's going to take a month maybe a month and a half just to get out of the seedling stage. I've never had seedling stagnate like this for no reason. Temp is 78f and humidity is 40%. Out of the 5 grows I've done the seedling stage or rooting stage for clones is the most complicated and annoying but it's never been this bad.

If you’re not happy start over. Plant right into the soil
The same thing is going to keep happening if I don't find out what is stagnating the seedlings lol.

You are overthinking it. Different strains grow different. Could also be bad genetics. Try Hydroponics. Growth rate is unbelievable and the environment is 100% controllable

But you might actually have different results planting directly into the medium. Transplanting can slow growth and wouldn't surprise me if it was the cause of your "problem". I've changed my thinking over the years and definitely transplant less than I used to, sometimes no transplant at all.

I only transplant once when growing in soil. And only after there is a well established root system
I have about 50 of these seeds from one strain of bud I got and I've grown them before with great results. Strain is zookies and I do grow hydro in coco coir. The only thing I can possibly think of is there might be contaminants or disease in this batch of coco I got? Should I flush the coco out with peroxide and hypochlorous acid or a lil bit of bleach?
I've always started seeds in a peat pellet I doubt that's the problem. I wouldn't consider that transplanting since it's so small.

The op said they were in Coco, which I'm currently running as well. I am indeed doing a single container grow from seed directly into the medium.
*Note; I did have some issues with the Coco drying out too much too quickly and my first seedlings failed. I added a small amount of vermiculite, just enough to surround a seed and planted in that. This completely solved my problem and didn't change my overall medium and strategy.

Not to be combative here but variations in seed, medium, nutrients, ect, ect. Can cause things to vary from grow to grow. That said just because you always do something a certain way doesn't mean you have to or even should do it that way forever. Testing different processes may surprise you.
All that aside some pictures and more grow info. To be honest so far you've given us little info to break down and we're all just left to guess on limited info. Also a list of changes or variations noticed would help breakdown the possible problems.
The only thing I can think of is there’s something wrong with the coco or the medium is taking too long to dry out. 2 of the seedlings are a little damp at the base. The coco still has moisture in it & I watered it 3 days ago. The one in the top left of photo is looks burnt so I turned down the light.

Never tried coco. I hear a lot of issues with it if it’s not set up just right. I’ve just tried a DWC setup and I’ll never go back to soil. I still grow in soil on the side. Got a little setup right now in a fish tank cabinet. Some skunky ass shit though!

Try starting them in smaller pots and feed daily to run off.
2 weeks from sprout and fed daily to run off.........coco should never, ever get dry.

Well I still don't know what you're feeding is like or watering habits or much of anything other than YOU think it's the Coco.
You do have a couple things going on here;
You have two showing signs of over watering. Note the curved dark stem, and the twisting as well.
Your other seedling is looking pretty burnt up by something going on.
These do not look like healthy seedlings. Without more info I can't really give any suggestions because I have no idea what your grow is like.
It might be that you need to just start over anyhow, sounds like that's what your gut is telling you. But if you want suggestions...

Also based on the limited info given I will tell you that peat is pretty acidic and can hold a lot of moisture, some peats more than others. Acidic would explain the burnt one, and holding moisture would explain the other two. I know you've been doing this and it's been working but it also dead on explains your problems.
A lot of people here will suggest not to mix peat and coco products. The reason in my grow that I chose to use vermiculite to help my seedlings is because it's neutral and free of nutrients. I watered far less than you would in straight coco at first and then once established I treated them like reg coco. Worked like a charm. Good luck.

Put clear cups on them as domes to increase the humidity.

Domes are for clones.
