Dark green/red stems

Way over fed would be burned it looks fine

Yes, way over fed, anyone who can't see this............

They do look on the dark side, but nothing to worry about. Some genetics have relatively light green leaves and others are naturally darker. I don't see any signs of burn or anything on the leaves, so look happy to me.

My Friend your plant Looking good .near the end will change color,no Problem

The leaves look great, nothing to worry about. Darker strains can have purple stems.
