Hi, i know you have many diaries and are not a total " noob " , but that soil is horrific.
You need to clean the soil out, take all the rocks away and make it more airy.
Air will not go throught that and make it to the roots, as roots wont be able to grow throught rocks!
This plant is so short and fragile im pretty sure the roots are not evolving..
Transplant it to a 10L min pot , clean the soil from rocks, throw a few perlite and mix it with the dirt and reeplant your baby again.
I promise it will double in size in 1 week and become healthy.
