my friend has indoor, and she was using Calgon water softener, they think the water is too hard. but the 'ladies' ;) didnt seem to like it. the leaves are all yellow at the tips and the soil is a nasty brown color, lots of shit. ph is 7. will they recover??? any tips?? thanks.
the pH is way to high if she's growing these hydroponically.
Water softeners can cause very high sodium levels and Ca defs- flush hard.
If the source h20 is 300ppm+, use a three-part nute ( GH, Advanced) w/ a specific hardwater micro- ( reduced Ca, Mag to accomodate higher levels in source h20), assuming that chem fertilization is required. In soil it might not be.
Another option would be Pure Blend Pro w/ the Cal-Mag omitted.
Seriously, flush the crap outta em, until run-off ppm is as close to source ppm as possible (3-5x pot volume).
Nothing but water for a week or so- those roots are gonna be mighty tender
They'll recover
