Welcome. One popped and you are on your way. When I use ocean forest, I tone it down a bit for seedlings. OF will also carry the seedling for a couple of weeks to a month before you need to worry about nutrients. You may want to check out basic low stress training. It will improve the quality of the plant and help minimize possible height issues.
Congrats and good luck
This is what I currently have going. Let’s Grow Some Purple Kush
