Seedling stopped growing

The smaller one is dead but the other looks like it may make it

So for the next seedling I should give less light, less water and no nutrients?

If those are over 20 days old you have some other problem.

What do you think it is?

Starting in smaller containers and not transplanting until they are about this size would have been better.

I have no idea of the problem but a 20 day old plant should look somewhat closer to this:

Hmm okay, should I plant them in soil?

Yeah, I know that haha. I’m trying to figure out why.

What soil is it. Need to know information.

Seedlings that size should only need like 25w if that. From what I'm seeing is you have been over watering and using nutes WAY before you needed them. You should not need nutes for the first few weeks. With those LED's your dehydrating your top inch of soil giving you a false sense of they need it probably. If you can safely check your soil deep would help eliminate this being a possible culprit.

Could be wrong but..

Hi guys, I am again posting a question here because my plants are dying again haha.
So, I planted two White Widow seeds a few weeks ago, I let them germinate and then I transferred them in coir to make the seedling grow.
I first used a 300W light for both plants, now I use two 300W lights for the two plants.
At first the plants grew pretty good, but at a certain point one of the plants stopped growing and became a bit yellow and the leaves seem dead and dry. The other plant grew substantially more but it seems like the leaves are turning yellow as well.
The lights are at 60 cm above the plants, the temperature is always between 23 and 26 degrees Celsius, and the humidity is always around 55%.
Wat could cause the plants to die. Is it too much water? Or too much light? I really do not know, and I hope you can help me.

Are you feeding them? There are no nutrients in coir

On the package is written that it has nutrients for two weeks, and it is without peat.

Could it be that the soild has too much nutrients in it? Because I bearly even gave them nutrients.
For the light I read that 300W lamps are okay also at early stages as long as it has the right distance from the plant.

No, I'm not, all the people here are saying I shouldn't in the early stages

Those people are wrong.
I start feeding light nutes daily to run off starting around day 3 from sprout.
Post #23 shows the growth in just two weeks with this method.......plus they're green.

What mick said.... coco needs nutes... other people are probably talking about soil.

Coco needs ph 5.9 ec of about 0.8 to 1.0 is a good place to start with strength.

He's already stated he's barely using Coco.

I forgot to mention that only a little part of the soil is coir, the rest is normal soil i bought from the store

To each his own but the cotyledons provide food for the first few sets of true leaves. Before the first 3-4 sets of true leaves your pretty much just pouring your nutes down the drain.

If your here and know what your doing then yes, go ahead and feed away as youve probably done it long enough to know the miniscule amount of nutes to use and how much to run off. But if you are telling a person who is having trouble keeping just seedlings alive to give nutes then you are wrong. This does not help one single new person trying to figure out how to grow.

Okay, yes it makes sense, I’ll try with the next seedling

Yeah I suspected that. Okay, so for now I’ll grow in normal soil, and when I’ll be a bit more experienced I’ll try other methods. Thank you so much for the help

Hope you know I wasn't trying to hijack your thread or start anything. I would definitely say explore other grow mediums but until you get the hang of them go dirt. Dirt is by far one of the more forgiving mediums. You def can get amazing results with other mediums like Coco but until you know it results are blah. Just grow a few in dirt and take some clones to learn Coco with. Stick around, ignore the bullshit and we'll all be following you soon enough.
