Hard Water Nutes-Autopots-Coco?

Hi all just after some advice on nutes i currently have 3 plants in early veg in autopots but having problems with my canna coco nutes not liking the hard water and having some deficiency's was thinking of changing to plant magic hard water and hope my girls come back nice and green? anyone had a similar issue or advice on a decent nutrient for hard water and coco?

well whats going on with the plants? also how bad is your water? are you using straight coco or a coco mix?

Auto pots feed from the bottom if I'm not mistaken?

Coco likes to be fed from the top with around 20% runoff.


Coco is realistically a drain to waste system.


You could have a salt build up in your coco.


What ppm/EC etc is your tap water?
