Konbanwa!
It is the second week for the big plant and the first week for the small girls.
I solved the issue - "what was wrong with them" - HUMIDITY.
if u take a look at the first week, u can see a big difference.
So I give them around 250ml-500ml of pure water.
I spray them before sleep with magnesium water. No fertilizers till the end of 3rd week at least.
Now the only issue I have, is that at night temp at some moment of time falls to 18. but I believe that it happens not longer than one hour.
Is it me or they are a little bit pale? I don't know.
@yokotasan, well it's only the beginning, there's still plenty of time to fix the issues.
Hopefully someone more experienced than me might be able to help you in the comments ✊
