RO came back with a build up instead of depletion. 1399 and was set at 850. Did flush x2 gallon got me 814. Left me a window of 136 ppm. Bembe gives me 23 ppm/gl and tiger bloom 68 ppm/gl . When flushing still have weak root structure she falls over . Suggested heavy on bembe for 0-1-3 to aid in her roots.
