I harvested it in December, so check out my profile and look at some of the pictures.
Once you get to growing, you learn so much! I’m excited to apply what I know now to this grow. This forum is a great tool, and has people with WAY more experience than me.

Depends on res size I’d snip leaves with damage off soon. New growth looks great almost like it’s running fine now just damage from existing issues.
