That is exactly what you do, @kw_Bat. Take a look at the forum rules and guidelines (esp. profanity and outside links).
Some folks start a new journal for each grow, others (like me), have a single journal that is maintained for multiple grows over time. here is a link to my journal: Merlin's Grow Log
Start your journal early and post details and photos. That way, when you need help folks will have an easier time figuring out what you need.
Good luck with your grow, we are all here to follow along and help as needed. Sometimes we help when you don’t need it. LOL
