    ya man do be rude its a forum he can post as he pleases as long as he follows the rules if someone trys this im sure they know the possible consiquenses as its a diy thing and its never guarenteed so you good sir need to smoke a bowl and chill

    I counsel against using sodium hydroxide. I use potassium hydroxide for the purpose. It's less of an issue in soil, but in hydro I like to limit sodium ion. cn

    I'll try to find the link for you guys.
    But WOODASH, disolved in some water.
    makes awesome ph up. And it has some super awesome micro nutes to offer also.

    Well, this isn't the read I originally found. But still quite good.

    Where's what I did. I took a small mason jar, used approx one cup water. I added maybe 5-6 sugar spoons of ash, mixed, I used an old medicine plunger, used a few squirts of my ash-water to balance two litre of juice.

    I guess you could mix your ash concentrate however you want. But that's what worked for me. I just trial n error'd that shit.

    And for how little I'm gonna use, for the few waterings in three months she will drink. I doubt much of a harm will arise from using it. But this is a test so who knows , I could just as easy do harm. I will report my findings here for you all.

    This thread was started years ago!

    I've used SBicarb for decades and have NEVER had a problem with it's use with Canna ! (I can count the times I've used UP on my extremities)

    As far as it being used with hydro. Your hydro should not be going down at all. It goes up and you set it back down. If your having problems with it rising. Better start looking for root problems!

    Hell kiddies. The stuff you buy is really no better for your plants then what you would use from home. In fact the normal contents of commercial "down" will hurt any Myco's/bio's your using!

    The bottom line is why bother with (very) possible injury from mixing dangerous chems to save a few bucks?

    Do I understand this correct? You have little need for ph up?
    When mixing your nutes,is it a base? are you mostly using ph down to balance?

    I ask, because I have the opposite issue. My juice, when mixed is (liquid ph test) is around 4.0 and I need UP to balance.

    Is this common to have nutrients on either side of the scale? Some needing UP, and some needing down?

    Could this be the difference between liquid and dry foods?

    Cheers all!

    Hmm. sounds like your using organic nutes? They are the only one's that I've had start "down" and need to be up'ed.
    What brand and line are you using?
    Whats the water at ?
    Adding a Silica? How?
    Baking soda actually needs little to do lots......I never had a problem with it in hydro!

    And Yeah, most and I do mean MOST need to be set down in hydro......synthetics

    Now if your pH is dropping instead of rising in your have a problem somewhere..

    I am using general hydroponics maxi-series. little bags of dry. Been mixing. My water is around 7.
    Yes growing in soil. Hmmp. Oh well. I do have a decent "organic derivative" ph up now. But I was just curious what other peoples food was at. Thanks bro

    The difference is water. If you have low ppm water, it's common that some hydroponics solution at normal strength to bring the pH of the reservoir to 4.0. With high ppm tap, you need pH down (unless you're using hard water nutrients).

    ChuffinHoolies Active Member

    Interesting. I did not know that. On that note. You mentioned that some hydro solutions "at normal strength" will drop low ppm water ph to 4. I am using approx 1/4 strength and still reading in the red.
    Our water is city water.from an old appartment building. I'm sure there has got to be some high ppm in there. lol.

    I guess I should invest in a ppm meter.

    I know your not meaning litteral, or that in every case that is what to expect, but.
    Do you have any links to help me better understand what is going on? With the water/nute/ppm/ph anomaly? (Could one half- assume that Low ppm water needs ph up,? High ppm water needs ph down?)

    churchhaze Well-Known Member

    High ppm tap water almost always means lots of calcium carbonate (lime) in the water. Nutrients that tend to be acidic will not be able to lower the pH very much because of the carbonate buffer. Yes, when I use RO or distilled water, I generally have to use pH up, but with high ppm tap, I have to use lots of pH down.
