Searched and Searched - HLG 320 with seedlings - recommenced height and powrr

I’ve used my QB for flower with awesome results, but for seedling this is my first time and I’ve seen so many different opinions.

im at 130/320 watts at 30”. In thinking dropping this down to 24” at 100 watts.

2x4 area in a 5x5 tent over 4 seedlings. I want to SCROG eventually.

thanks!
