Go into " indoor grow journal section" page 10, I have a journal with Fitzy genetic and that journal is mark "complete " mark in red. A mod. completed that journal. That's what I'm talking about.
I don't think this is the norm, it's something you can do yourself. Mods aren't keeping track of everyone's completed journals, they are struggling to even keep battles going as it goes. There was a count to determine what level to start peeps on but that was mostly based on trust AFAIK
