Help! My PPM drops without adding fresh water

[Laid]

I'm running a aero systems that I built with a 50 gal
rez. Second week into flower my PPM starts out at
750 with AN 3 part and in two days the PPM drops to
600 ppm and 40 gal. Should I just add RO water or
should I add nute water? I also use cal mag. Thanks

What your information tells me is your plants are hungry for nutrients

Nutes are being used up. Add RO to the original volume and take a reading. That is the only way to determine how much was used/needs to be added. Gotta compare apples to apples......
