Not to change the subject, but ok, was just checking. I'm doing fine with fabric pots so far but we'll see. Status of the roots still remains to be seen. I haven''t got the salt stains taco got. I definitely don't water large amounts and get next to no runoff. I'm in soil. Don't know if Taco is or coco? I nute every other time I think at 800ppm. What ppm you watering taco? Or maybe the stain is something else in your tap? Do you keep reusing your fabric pot over and over and if so did you wash it between? I'm just asking because maybe that stain is a good clue to look into further. I mean white could be a salt. Wonder what else is different about the flora line. Was the stain with flora or with floranova?
