I go back and forth with this too, gets too complicated. Count the days. Day 1 is sprout, that’s when seedling stage is 7 days - I use the germination week in the diary for this time period, week 1 veg in the journal is week day 7-14 - week 2 is day 14-21 and so on… helps me to remember what week they are actually in! Good luck Growmie 👊🇨🇦❤️🌱
