TDS numbers; understanding

Here’s actual Ph/TDS numbers:

Feed water IN: 6.55/2300

Runoff:
Plant 1-6.34/1540,
2-6.2/1940,
3-6.21/1650,

I would run some water only feeds and let those numbers come down closer to 1000. The autos I’ve ran didn’t require/like heavy feeds. They did best with runoffs around 1000.

Ok, Thanks, I’ll try that!
