I'm in pro mix bx, with coco loco. About 70/30 with a hand full of ffof on top. I ran just under 2 gal of r/o water that was at 6.2. Runoff started at 5.7, final was 6.2 with a tds of 695. Should I run more through her? 3gal fabric pots.Flushing to save a plant may or may not be useful, but worth a try. Sorry, I don't remember, are you in soil or coco? At this point, if it were me, I'd flush with a mild nutrient solution, say 200 ppm. That way, the plants don't starve.
