How Long Will It Take?

A customer has a question and I hope we can get some opinions on it, thanks.

“I order some growing soil,but I don’t know how long il take thanks,and can u help me about my plant is nearly 4 weeks and is still not growing its small and only 4 leafs is normal?”

Pictures help immensely! Depends where you are located, and who you ordered your soil from,when you receive it.
What are your plant in at the moment?
