First Grow Ever Scared As Shit

Shaybaby I'm very new to this and would love any feedback it would greatly be appreciated. This is my first grow ever so I feel like I'm already making mistakes. It took 3 days for my seed to germinate and has been in soil now for almost 2 days and it has not come up through the soil, what am I doing wrong or is everything going as it should so many videos I watch have so many different things it's all so confusing. New Update as of 1/22/20 she is starting to pop up through the soil I hope that's what she is supposed to look like any suggestions for the next week with her.

Shaybaby My seed has finally fallen off and I am now starting the seedling phase does anyone have any comments or suggestions for me for this stage all comments welcome. She is finally open and ready to grow strong hopefully she keeps going if anyone has any comments about my yellow cotyledon leaf I would really love to hear them.

Shaybaby This starts week 2 of seedling stage she seems to be coming along very well if anyone has any comments please feel free I welcome all comments and suggestions. (UPDATE) So not sure why but she seems to have stopped growing vertically and was toppling over so I had to use 2 metal skewers to stop that from happening any suggestions to make her stem stronger?

Shaybaby She seems to have grown overnight shes not tall enough to low stress train her so I'm using skewers to separate the leaves so all the nodes can get some light I hope she is where she is supposed to be any comments are welcome.

Shaybaby Shot up over night so happy with her so far have a couple spots that have nute burn but other then that's she's doing great. (UPDATE) Sorry I haven't posted in a few days been super busy but I just updated pictures of her I think she is filling out great Do you guys have any comments)

Shaybaby She seems to be starting the flowering stage I would really like any possible feedback since I know this stage is very critical I don't want anything to go wrong I got this far.
