    Default Unanswered: Brutally Hard Water

    What's the best way to deal with really hard water. My water is well water and I border a coastal estuary. The water is very hard, high in Sodium, Calcium, Magnesium, Manganese, and Iron. The water, straight out of the tap, has about 750 PPM of dissolved solids. The runoff from one of my 7.5 gallon pots is 3300 PPM. I flushed the crap out of it and got it down to around 1100 PPM. I am thinking that I need to start watering and feeding using distilled water. So far no issues on this grow, but last year I had a terrible time with the bag plants during budding with plants turning yellow and not doing well. I'm growing in amended soil and in Fox Farm Happy Frog. The two in soil are in an outdoor greenhouse, the other two are in 7.5 gallon pots in the garden. They are just starting pre-budding right now. Any advise would be great.

    If your ppm has risen that much then I suspect it is feeding at issue

    Are the plants nutrient burned ? Is this why you checked the run off?
    The background ppm is not ideal but should be factored in so you would expect to be running a higher total ppm than what is considered normal.(Although that is very high and a good watering will get it down)


    I’ve never been a fan of checking runoff.It adds to problems if u ask me.
    Use the plants as your guide.If they’re looking pale feed them,if they’re looking dark green back off.
    Just regular feeding with what it says on the bottle with regular watering s in between is the way to go.
    Using the weather as your guide as to how often that is.
