hello guys they are currently 9 days old. But the bigger one is sick i guess,their leaves curling upward so bad. I read rapid growth may cause this,any idea how can i fix it?
Thanks for comments

not 100% positive on this but my thinking is the humidity is a bit low 50+ would be better and maybe a bit of heat stress nothing too big too be worried about but try raise that humidity if possible

Should i add calmag now? or is it too early? Im dealing with heat stress now

id hold off on the cal mag till you need to use it plants loo good apart from the the curling i honestly wouldn't worry about it now unless it continues on the new growth but keep that humidity up best you can once it get a bit bigger she will be able to handle the stress better

Option 1)...rotate the plant with another.
Same issue on plant 2?...raise the light.
If the plant has more leaf curling( plant1).
Start feeding a little epsom salt (50-70ppm).
Curling or deformed leaves are a first sign to magnesium def'c.
