Hello and Happy Thanksgiving Eve ... 
I have (2) mother plants which are no longer looking healthy since their nutrient solution was changed about 10 days ago. I did look at several diagnosis guides provided on this forum and have some thoughts about what the problem is, but since this is my first time giving this a go, I would appreciate additional opinions! What is the cause (or causes) of the problems shown in the picture and what is a recommended fix?
