I reckon there are several things that could cause it. Where my concern was/is, it wasn't hitting the the whole grouping (one particular variety) it was hitting one or two out of the many different ones spread over a large area. It's not been overly humid and hot here... so taking everything into consideration and what all I was risking by leaving them there, I dug them up and disposed of them. I hope that takes care of whatever the issue was, I guess I'll see further down the road if it did.
I appreciate everyone's thoughts on this matter!
