I don't know what Serenade is so I cannot comment intelligently. However sometimes a plant will transpire when cut like this... ever seen an Evergreen tree with pruned branches? They weep for a while and then heal up on their own. I would watch closely (as you are) and resist the urge to just chuck her out the window on a whim. Be prepared to react if it gets progressively worse, but monitor, compare, wait patiently, do it all over again.

It reminds me of last night when my sister called in a panic. Her dog Mabel was hit by a car and my sister was crying, emotionally distraught, and needed emotional support. She was at the doggy ER and there was internal bleeding, not sure whether to operate and they said it was 50/50 survival if they operate... we (Mom and I) told sis to ask a lot of questions, assess her skeletal and neurological functions with the vet, and then call us back.

Well, Mabel (sweet lil Rott mix) had no broken bones or fractures and brain functions were normal. Sis decided to wait and see how she made it through the night. Today we heard back that they chose not to do surgery or anything and her bleeding appeared to stop (so far) and it seems what was needed was time to stabilize and make a rational decision. Mabel will stay over today for observation but she is a lively, strong 10 month old and that is helping her heal.

So, long story short, perhaps Kushette is also a strong lively soul that needs a bit of time to stabilize.

I cannot speak from experience revegging but the plant just went thru a great trauma and may be exhibiting a short lived effect. It also seems that if it were mold or fungi that it showed extremely quickly, but again, I am not an expert on this either.

At any rate Weedhound you have a green thumb and care a lot for Kushette, so watch her closely, monitor changes and be prepared to remove her if things get out of control. But know that living things that are strong can often heal themselves at that may be happening...

Just a though, I am not experienced in revegging. I am just applying reason to the situation.
