Im flushing with well water and ppm is 480. Runoff is 650 for one plant 680 for another. 960 for last plant. I could never get 100 unless you subtract the ppm of going in from water coming out. Is this what i should do. Ph is 6.7 going in and 6.3 coming out. Plants are looking awesome so i assume this is okay. But could never get ppm down to 100 or less of runoff.

Flushing before harvest right? Around 100PPM is general guidance. If you're over that, that is ok. These days many growers don't flush at all before harvest. It's a highly debated topic.
