Hi, if you plan on entering contests, I would do three separate. Otherwise if the feed and everything else is the same, just do one. GD prefers single strain diaries for contests. Good luck! ✌️🏻💚🌿💨
Totally a personal thing man.. if you’re doing it to actually document your feedings and nutes for different ones for your own documentation.. might help to do separate ones but I do several in one just cuz updating each one separately can become tedious
