Is my conure sick again!?

hello, about 2 weeks ago my dad bought me a Patagonian Conure! he fell ill on the third day, so ill that he was close to die so i rushed him to the vet and they had him on oxygen and vitamins! they didn't know what was wrong with him because he passed the health check by the same veterinarian when i first bought him! anyway, after four days in the hospital he surprisingly recovered actually he is acting way much better than when i first got him! he is more active, eats and drinks fine.. he does what every healthy bird do i even got to teach him to say hello and meow (though i never meant to teach him meow but he picked it up really fast from Tv xD) oh and he also loves to bath he bathed hims self two times this week! ..but you see the problem is i noticed his droppings changed in the past two days the feces are formed fine its just that most of the urine looks kinda cloudy little bit thicker and its color is (off white / pale green) i dont know if its because the urine is mixed with urates.. though there is just a little bit urates stuck on the feces but still i wanna make sure if there is nothing wrong!! oh and sometimes it contains little bubbles in the urine! .. i read that bubbles in urine are caused by gas or bacterial infection! and colored urine indicates liver disease!!... so is he sick again!?.. the vet in our town is not an avian vet but he has experience so ill give him another visit this tuesday! so i need opinion on this!! what do you think is wrong with my conure!? :'(

what are you feeding him??

no human foods/snacks, are pellets high in colour?? waters fresh in clean bowl every day!

but vet visit would be best

No human food/snacks!! just seed mix and fresh water everyday!! i do give him fruits though he doesn't eat much of them just the watermelons and little bit of the oranges!!
