Problem: My seedlings are taking forever to grow and I'm not sure what to do about it. They sprouted 2 weeks ago and the growth has gone to a slow crawl lately. The cotyledons are turning yellow and the new leaves seem brown at the edges. Can anyone please lend a hand?

Here are some pictures from today

Lighting seems sufficient and nutes aren't needed really. Not in any large amount at least. The only things that come to mind from my own experiences are wet soggy potting mix, the roots need air. Or it could be bad genetics/seed. I've dealt with both before. You can change/fix one issue but not the genetics. Just what I've run into myself. Good luck.

Let me add that the above comment is assuming you're not feeding anything but water to your seedlings.

Thanks kgg634. Would you suggest feeding nutes now that the cotyledons are turning yellow?

what kind of dirt? if its in soil, no. if its something like promix or sunshine, sure. but very light. it needs to get healthy before it can handle anything more than bare minimum

 

[Stunned]

is why I like using coco for a medium
they get nutes as soon as the first true leaves form
and they rocket with the right light, RH and temp
soil is so picky
coco, just soak it every day with nutes
easy peasy

 

[CannaCola]

also why im starting to love DWC

 

[Stunned]

DWC is also too picky

 

[CannaCola]

i disagree. i find coco more picky. though i agree dwc is a bit more effort to set up .

 

[Stunned]

I'm just being a dick
Once I feel really comfortable with coco, I'm going to try DWC

Two weeks from planting, or two weeks from busting through the surface?

How far is the light from the seedling? Should be about 24-28” from the plant at this point.

Are you letting the soil dry out before watering?

What’s your RH?

The plant looks fine despite the slow growth. No need to panic with soil, it’s forgiving, just don’t do anything crazy like blast it with nutrients.

The cotyledons are dying because they have done their job. Nothing wrong there

gimme a break!
If the pic he posted is 2 weeks of growth from germination, then something is way whacked
yes, there is reason to panic, if he doesn't fix this, the plant is done
I'd force feed it
like how you make foie gras lol

]2 weeks from bursting. the light is about 18" now. yes i make sure the soil is dry about an inch below the surface before watering. RH is about 65%. what would be the downfall of giving nutrients now?

 

[Stunned]

Is the soil charged?
light is good for a seedling
watering with soil, you have to be so careful
I think it needs nutes

 

[ostrichzigga]

soil is not charged i don't know what that means

[Stunned]

you can get soil that has nutes added to it
as opposed to just plain soil
I'm just wondering what your seedling has to work with

An inch below the surface is not enough. Gotta let the roots search for water. Particularly if the container is bigger than a solo cup at this point.

Seedlings don’t need nutrients at this stage, not with soil. What kind of soil is it? Potting mix?

There is new growth and it seems healthy. Only a fool would panic at this stage. Let her dry out a bit. Get into a routine of watering and letting it dry out. Not dry to the point of wilting from thirst but, enough where the pot is lighter. If it has been overwatered the root system may not be large enough, gotta make it work for its water, bigger roots bigger plants.

It may be a slow starter. If a few wet dry cycles don’t get it kick started then it may be genetics.

 

[Stunned]

at 2 weeks old, that plant should have way more growth than what is showing
even if it was planted in concrete
it needs nutes

 

[Advocate420]

What are you using for water and what does it test at?

And for good measure, because you aren’t getting enough conflicting opinions. Your light should be at least 2 feet off of your seedling. I’d start at 3. Make sure only your veg switch is on. Also make sure your plant is getting some fresh air.
