Seedlings need to be kept a little warmer...try 78 as your low 80-82 high.
Keep them moist but not soaked.
Good luck.

I’m curious as to what sow is as well, at least in terms of soil. But did you happen to have them in a dome until they broke the soil?

I don’t know I used google translate for that one :)
It’s basically ground and sand without any additions. Special for seedlings etc. I just don’t know the English name for that stuff
Your English is muuuuch better guaranteed! than my speaking your native tongue...you are good.

They look like some nice seedlings, remind me of shishkaberry ones I had. Yeh most of them look dry but don't overdo it at this stage

from the store, it’s from Pokon. I don’t know if you know that brand. It’s quit big through.
I think that may be your problem. Here’s the NPK ratios for that soil,14-16-18. WAY TOO HOT for seedlings. I would advise getting soil that doesn’t have any nutritional values in it.

My


On the website it says NPK 10-4-4.
So I must have seen a different soil than the one you have. Even still, seedlings that young don’t require much in terms of nutrition. I usually don’t start feeding until at least 2 weeks after they’ve sprouted, and a very minimal amount at that, that’s the problem with soil that has Nutes in it. You can’t control the feeding.

If you have a humidifier, you should use it. Humidity should be ~60% because the root system isn't developed so the seedling needs to absorb water nutrients from its leaves.
