She is looking good and healthy, but please move her to a minimum 5gal pod or whatever size you have planned to be your final pod ASAP
For the first and second week for won't see much deverlopment because it trying grow root zone as much as it can before it grow upward
Week 3 to week 5 you will see she grow very fast, cut of the first node and LST it as much as you can. This week 5 she will start flowering
if you go with light 20/4 all the way, please make sure you have Cal-Mag ready, you will need a minimum 1cc for every water all of the flowering stage
Good Luck
Cheers
Sunny
