Begin to introduce her now to all sorts of foods,if you leave it she may refuse as she gets older,it's far easier to start when their young.Perhaps offer her the tropical fruit mix & add some fruit to it,i would leave her a bowl of pellets out so she has access to them at all times,i dont believe in feeding at set times.for dinner/supper try offering warm veggies,carrots,broccoli,peas sweetcorn etc.. you could mash them slightly for her.Try some cooked beans,pinto soya etc.. they generally are a big hit.You can always try things like pasta,rice mixed with a little scrambled egg.. have a good look around the bird food room, there are various threads on diet.
