Slow Growth and yellow leaves

[Bim024]

That soil looks like one of those compressed bales of Promix, 90% peat. The plant still looks fine to me but which soil is it?

It is regular plant soil that I bought from OBI.

I hope these Fotos will help.

take a pic from a side angle so we can see the distance between light and plant

 

[GNick55]

find on the internet the soil you used and copy the picture to post here

I think its doing fine, stem isn’t stretching, new growth leaves. Shes building roots. I would use the finger to the second knuckle (or deeper) method for watering.

Better ? (This is the best I can do)
I threw in that ruler to get a more accurate estimate.

Yeah, kind of. I mean it has it first set of leaves but they aren't that big yet, and the last two days they've been slowly turning a bit more yellow. On top of that the Growrate is much slower than it was before.
And as you can see you're seedling still has its cotyledon and is older than mine (and it's still green).

And what is that method for watering? I never heard of that before.

Stick a finger in the soil up to the second knuckle to feel how damp the soil is down at the roots. You can tell by lifting the pot of soil too, water when its light, very light, then water slowly for saturation. I don’t like pots that can’t breathe but other growers do use them.

If anyone is still in this thread. Than here is a small update. Here is a little comparison form my little princess from two days ago and today.
The first Foto is from two days ago. The plant is a bit smaller and has fewer yellow spots.
The second Foto is from today. Yes the plant got a bit taller, but to less for two days. And the yellow spots got much bigger.

Now my question is, should I repot this seedling or not? What's your opinion on this ?

any “damaged” leaves will not heal itself..
it looks to me to be light stress..

The tips burning is most likely light intensity and nutrient strength. She is taking a lot of light and eating and drinking more burning the tips. Lower intensity and keep using nutes you mixed OR back the nutes you just used down a bit.

 

[Bdubs]

The first set of leafs are not fully yellow yet. So nutrients are not necessary. But since you did, give her a break. Drop the nutrient strength you just used and let her cruise for a week on that.

 

[Bdubs]

If light intensity is good you can check your RH, if it is low she will eat/drink too much and burn as well. Increasing humidity will in turn slow her need to drink more from the roots for her water also preventing nutrient lockout and rising PPM in the soil. She will “drink” through the leafs and seek nutrients from the soil and drink less water out of the soil, creating a balance. Manipulate her metabolism and resources to manage her rates.

nothing to do with nutrients.. it’s the light or heat..
whats your temp and humidity?..

I would not repot yet.

What's your lighting schedule? Looks to me like it needs a break but there's way more experienced growers in the farm. Listen to them.

Temps. around 25°C
Humidity I don't know and cant really test that

Its on 18h light and 6h dark, I think

Idk why or how I would know this but those lights look quite intense. They might be drying out the soil thus concentrating whatever nutrients that come in contact with the roots. Whats the humidity in there? From someone that lives in a dry climate it looks like 20-40%? And on a windy day that number just plummets. Plants at that age prefer anywhere between 60-80% humidity to sustain a healthy growth rate. I would suggest trying just 1 light. I start single seedlings under a single cfl (compact fluorescent lightbulb)
it's only 36w. Same bulbs for homes and bed rooms.
And I also cut the top off a 16oz/500ml water bottle shaping it like a cup and using that as a humidity dome. Some people suggest to remove it right as the seed sprout but from personal experience if your light is close or too hot, they prefer to remain inside the cup for atleast an extra couple of days after sprouting. And even after that I see some plants dry out too fast and have had to place the cups back on a couple days more.

Sadly I can't change the light, but I turned it dow as much as I could. I don't know the humidity in there, but yes it's pretty dry. I will do that bottle thing, but shouldn't there be a hole or so at the top for airflow? And I sprayed a little bit of water into the Bottle, so it raises the humidity.

Also spray around the plant so the soil also moistens up so it gets warm and humid. You could poke holes but I myself don't if it's hot and dry the moisture escapes. What I do do is remove the cup an hour a day once maybe twice so the soil can get oxygen to the roots, then place it back. It's becomes a dance.
