First Outdoor Grow Issue

What's good, People?
'SWV' is the name of my seven foot Strawberry Diesel first outdoor grow. They were doing fine until I found a few stink bugs on one of the stalks (the far right) a few weeks back. I knocked them off, used Neem oil on the area and now, the same stalk is turning brown and some of the branches on it are dying. Anyone know what I can do to fix this?
?

Neem should only be applied at night or it will burn plants

Also man, I’d encourage you to top your plants, rather than being super tall and wispy they will be short and wide i top all of mine! Multiple times actually, and if it’s an auto like in the tent, I just tie the top over with supercropping and continue that method! Increases yields bc it breaks the dominance from that one main cola and give it multiple instead! See the pics I added for reference! @Truth11234

Stink bugs are harmless and spraying neem on outdoor plants can kill helpful predators

Check to see if there is signs of stem borer along the stalk. Why did you cut off all the fan leaves?
