Hey man if you're just talking about those small bumps on the stem, thats nothin to worry about. They happen as the stem gets thicker and wood-like. Mine have that all over them, i like squished some to see what they were and it made my hand just straight stink like pot.

I'd be more worried about the yellow leaves than the stems. Looks like she might be needing some N? What you feeding her? Overall they look really healthy though, beautiful plants. Are those 5 gallon pots? Your plants really should start to explode soon, once they finish filling those pots with roots, they'll take off. Like a week or 2 after we transplanted to big pots like that they started to just grow like a weed lol. Stop by and check out the log in my signature, I'm a first timer

Oh, and welcome to the boards :jointsmile:
