So what do we consider a large change in conductivity?
After 4 large water changes and sporadic dosing of EI macros (daily dosing) my TDS was stitting at 250ppm before the last water change.
After the water change (about 80%) it was 125ppm and now another day later is 138ppm.
My tap is 60-70ppm. Would you consider a 70ppm shift from a baseline 60-70ppm to equal by now approx 140ppm a large change in TDS?
Would my TDS sitting up at 250ppm indicate that my plants are not using many nutrients and that they are just accumulating? I change water every week, feed once a day and I'm lightly stocked.
Thanks
