If a leaf is sick on a plant, you do not deal with the leaf. No, you go to the source and make sure that the proper growth is happening.

Snot nose kid was the leaf... The source of the issue is being looked in to. In time, this plant may become healthy...

All in all, a good outcome.

Edit. This Way of the Gouda is paying off. Wise Master Sri Reepah Gud Won would be pleased. I must be inching closer to eventual enlightenment.
