Hello all,

A friend of mine recently purchased a single Salvia Divinorum plant, it came as a rooted cutting.
It was in pretty sad condition when it arrived, had many wilted leaves and was pot-bound.
They cut off the sad looking larger leaves to stop the plant wasting energy on those, it was re-potted in a bigger pot and is now growing indoors. It is just going into summer here and it is not very humid so they have been misting it 3 or 4 times a day and it has been getting 6 or so hours of morning sunlight half filtered by some light curtains.
It still looks quite sad though, it has been re-potted for about a week now, and it still has some curving of the leaves and some wilting, there are brown spots on the leaf as if they are dry spots which then sort of disintegrate leaving an open hole on the leaf.
It has been doing that since they got it, and it not having stopped has them concerned.
Some of the leaves also have brown tips, including new growth.
There does not appear to be any insect infestation, however today they found a single miniature caterpillar and removed it.
I was wondering if I could get some advice to help my friend, a few things that came to mind were:
1. Perhaps a higher humidity is needed, thus a humidity tent.
2. Needs more sunshine
3. That single caterpillar has a bigger apetite than your average elephant.
4. It is just taking its time growing in to its new environment.

Many thanks in advance,
Peace and happiness find you all.
