Help with flushing

So I was apparently watering my plants in coco wrong and the salts were building up but I caught it in time before lockout or burn. The EC was pretty high tbh. But I flushed with nute solution diluted to half strength of what I would normally give. My normal inflow PPM would be 600 so I flushed with 300 PPM solution. I eventually got runoff PPM down to 600. Is this the correct way? Or am I supposed to be getting the runoff down to around 300 to match my inflow and then continue with normal 600 ppm fertigation thereafter?
