How Does One Tell the Difference between Salt Discharge and RI Discharge?

[Betta_Koi]

Hi everybody,
My chameleon has had some white discharge around her nostrils the past two days and has been slightly lethargic (I think...her bugs are gone so I believe she's still hunting and eating). I've been reading it could be excess salt being discharged but I have some experience with RIs doing the same thing. She's not wheezing or popping and I have accidentally over-dusted her bugs the past couple day. Is there a difference in colouration or ease of cleaning between salt discharge and RI discharge? In other critters I've noticed more yellow colouration but are chameleons the same?
She's also been by a window since I got her but I've moved her because I was worried it was a respiratory infection from getting too cold. I'm still pretty new to this chameleon thing. I'm used to desert critters. Any advice would be appreciated.
Thx

Dry white powdery substance around the nostrils are salts. When chameleons have an upper respiratory infection they usually blow bubbles out of their mouth or have foamy saliva around the edges of their mouth.

I was concerned with the same thing....don't mean to tag or change subject, but want to show a pic of my guy that has salt on his nose! Glad to hear its only salt and not an URI!!

Best things to look for after having to deal with it myself... I didn't see the mucus until a bit later while he was getting treated.

Gasping/Yawning, squeeking while breathing, mucus, and if they crane themselves upwards while sleeping.
