My best advise would be to take it to a good nursery, and have them tell you what you are dealing with, and the best approach to a fix. Kind of like me telling you to go have your spleen removed, due to an internet conversational diagnosis, I don't want to tell you that is or isn't the only answer and something else might be there. I don't recognize your spit and hoppers, because we don't have em here
.
Best of Luck
Let us know what the results are, so we can all learn.
