them orange spots are not a bug they are where abit of feed or something has got on the leaf staining it the light purple stains are a very very very slight defiancy in potassium in my opinion and for a plant this large this is common bugs will eat your leaves and there doesnt look to be any signs of that here if you want to double check little buggers like to hide on the underside of leaves so turn them over and check but i think this will sort itself out :) best of luck 👊
