Top my lemon bannanna sherbet today she’s patiently waiting in line for her spot in the flower tent getting to tall so topped her. The stem is literally like a soda straw in exact proportion completely hollow I’m afraid of it being exposed on the top like that. I just put a small piece of tape to cover the opening at the top of the stem anyone have experience with hollow stems?
I was getting ready to say that I saw someone recently that had the same issue. Now I remember who LOL 
. Like @Bow4Buck pointed out as long as she’s healthy there’s not much that you can do really.
No pith is actually considered a superior plant by a lot of growers.
