first time grow updates and questions (mine and yours)

this is my first ever grow, things are really coming alive but i still have some questions and things to share. feel free to add your own questions or share some of your success. I'm gonna start off with something i noticed today... a new node with 3 leaves forming instead of the regular pair of 2. does this happen to all plants, not including the growth between the fan leaf and main stem my top is pushing out 3 leaves while all the bottom nodes have 2.View attachment 3033908
