Air conditioner drains white discharge

That's normal I do HVAC service all kinds of crud build up on you're indoor coil over time and fall off plus bacteria and other stuff grow and thrive it's normal but you may want to clean out you're drain or get a company to do it before it gets clogged up .

Thank you all for your suggestions . The water sample did not show any salinity . I changed the pipe and can no longer see any white discharge . I can only conclude it was some kind of garden fertilizer or chemical that may have cause this.
