Stemz

Hiya folks! My plants are workin on their fourth set of leaves, however the stems still look to be about the same width that they were when they started growin... and one of them has a ziz zaggy stem and looks a tiny bit sickly.

Do I have anything to worry about? I heard that real stem thickening doesn't really happen until later on, but i'm still a bit worried

At that early age you should be okay, a pic would help. Do you have a fan on them already?

I don't have a fan directly blowing on them, but there is one beside them circulating air. They sway in the breeze, slightly.
