Tibuchina problems

Recently bought this bush have it in a conservatory no ventilation I have this problem already surfacing on the leaves is it red spider mite no webs can be found underneath?

 

I've only grown this plant on one occasion, I thought it was a pretty easy plant to please.
It's not really possible to say whether it is red spider mites or not from your picture.
I assume you are referring to the rolling up of the leaves.
I think you do need give the plant some ventilation and as bright a position as possible, but full sun with no ventilation is not good.

 

It looks healthy enough. They do like lots of water in the growing season, especially if in the sun.
