Hi,
I got this zenetti blue pericallis abt 4 months ago. Leaves started having this white shade and turning yellow when i put the plant outside, at that time it rained often. Outside also received strong sun morning until early afternoon (east/slightly south facing).

I thought it was problem also with it outgrowing the pot (root was going in circles in the original pot). So i moved it to a much bigger pot, and moves it away from intense sun (put it in an open shed, that receives a bit of morning light). No improvement (maybe slight deterioration).

Today i took it out of pot , the roots seemed to have shrink. i just drenched root in water today.

My question, is this plant diseased somehow? Is it beyond repair? If anything i can do to try to revive it (i would like to try if any way). See pics
