Seedling troubles: 5 days and very little growth

[Zebidee86]

Hey everyone
Just looking for a little advice/reassurance. I’m growing a Barneys farm OG blueberry fem in coco, it’s currently in a pretty small pot after a perfect germination and it’s been about 5 days since it sprouted.
The last couple of seedlings I grew were autos and this is my first photo strain.
I’m growing indoors in a 60x60x140cm tent and using a 400w LED about 15” above the plant, the light is set to blue spectrum only, temps are 22c and humidity fluctuates between 55% and 60%.
This is the 2nd seed of this strain that I have sprouted after the first keeled over and died due to damping off, so I’m a little jittery about this one as I’ve had bad results previously.
I’m getting the feeling that this grow is going to go tits up as there has been very little growth in terms of true leaf development, it currently has one set of the first true leaves, and they aren’t growing very much. I don’t know whether it’s down to the strain or if autos develop their first few leaves sooner than photos, but I feel like the last few grows were growing a new set each day and this one just seems to be stalled.
It looks to have a bit of stretch to it as I mistakenly thought starting it off under a windowsill would improve its chances. There are also roots beginning to show at the drainage holes in the bottom of the pot so it seems to have grown below the surface but not much above it.
I’ve given it a very weak feed of biobizz grow and some calmag just in case it’s due to coco being too inert, however my last coco grow didn’t get fed for at least a week and showed more seedling stage growth than this one.

What’s the best thing, if anything, to do?
Thanks in advance

It looks fine, but wouldn’t be a terrible idea to get it under some form of a humidity dome. Also, just make sure not to drown it and you should be fine.

The seedling looks fine. You might consider adding 30% perlite to your coco when you transplant.
Perlite = aeration = more oxygen to the roots = fast growth.
I like to feed daily to run off from sprout.
Good luck.

Thanks for the replies, I feel better about it now, I did have a humidity dome over it, maybe I took it off too soon

 

[MickFoster]

A humidity dome is great for clones but I wouldn't suggest it for a newly sprouted plant or a germinating seed - bad things start to grow under very humid conditions. I don't see humidity domes in nature.

 

[Aroxol]

Disagree, but I’ll politely say do what you feel is best.

I wonder if there's anything about growing weed we can actually all agree on lol.
Im with mic though , always water to runoff every day. Coco can go tits up pretty quickly if you don't .

I agree with Mick. A dome for clones, not seedlings.

But the time you see action topside the roots are already there. The feeder leaves have what the little girl needs.

Besides she already is getting her first leaves.

She looks great. Just be sure your lights are at the proper distance and don’t over water. If you haven’t yet done so I recommend reading the sticky.

Again, thanks for all the advice. As far as transplanting goes, do I use slightly bigger pots until the final pot or should I shove it in its final pot once it’s established?

 

[Sctanley007]

Either will work but up potting to a 1 gal then to final pot establishes better root structure imo. Plus gradually increasing pot size helps curb over watering.

I put seedlings in final pots right away. No more transplant shock for plant and water with nutes by hand twice a day for the whole grow. I always water with 20-30% runoff. You cannot overwater coco which keeps being repeated.
