One thing I found with 18/6 and autos. Seedlings stretch fast. I’d recommend using 24 on for the first 7 days and leave yourself enough room in the pot to add medium. Once they are lanky enough to look like they need support add medium to shore up the stem. Then flip to 18/6 for the remainder of their life.

I go by Lux using a light meter app. For seedling about 7k - 10k lux for the first week of sprouting. They are gonna stretch. Be ready to support it. I like to top dress with more soil when it gets to lanky. Having a fan moving air will help develop stiffness of the stem.
