Bought this outdoor plant 2018. Don't know name. It was sml & grew slowly so I repotted into lge pot using Searles best soil. It's around 1m now. Was healthy with glossy green leaves & flowered all through summer. Now leaves are pale to yellowing with black dots, feel rough & is very sparce, not thick foliage. I've tried Seasol to no avail.
What's wrong with my plant ????
Pls help me save it .......
Attached photos from healthy to sick.
