    could be. i'm gonna give MC another shot and before I re-try, I'll sanitize my res.

    so you don't think the humics are doing it? just seems that it's an acid and "should" lower the pH.

    No, I don't think so because even with acids and humic acids, they should be relatively stable once mixed. Also, right now MEGA CROP does not have humic acids (we may consider adding it later), the reason we did not include it was because it can clog drippers, and also it usually only benefits growing methods that use a physical medium (like Coco, Soil, Peat Moss). So technically it doesn't do much for DWC/RDWC or Aeroponic, so we wanted to have maximum compability.

    Also, the main job that Humic/Fulvic does is chelation and improving soil so ions can be absorbed better, however we instead added 18 L-Amino acids which do the job much better of chelation and have a higher performance effectiveness (also they are compatible with all growing types, including RDWC). So if you notice the brownish color, that is probably some of the pure L-animo acids (not humics).

    PH should be stable, are you following these steps?
    1) mix nutrients well in water
    2) wait 30 minutes
    3) PH balance to your desired level

    From here they should be stable. I do believe you that you have having drift, I am just not sure what is causing it yet!

    my bad, i thought i read that it had humics in it. that theory goes out the window! lol.

    my mix method is to let it mix in the res for at least a few hours. i usually mix up mid morning, let it mix until about 5pm, adjust pH and first feeding is at 10pm.

    that lowering drift that i have seen was with both RO water and well water so i don't think the water is a factor.

    hey Rky

    1) what products do you use for PH up and PH down?
    2) comparing when you used MEGA CROP and Maxi, did both products give you the same initial PH after mixing? Or did they give you different PH? Do you remember the PH levels before adjusting for each one?

    trying to troubleshoot whats going on!

    1. GH ph up and down.
    2. it kind of depends what water i used. i just mixed a batch 2 days ago with Maxi so it's fresh in my mind. 15 gal well, 37.5 grams maxi and after it mixed for a few hours pH was 6.5ish to 6.7ish.
    if i remember correctly, when i used mega crop last time, 15 gal RO, 52.5 grams MC, pH was 5.3ish. dont' quote me on that cause i do smoke a shit ton of weed. lol.

    i'm gonna mix a batch up of mega again in 2 or 3 days and i'll document everything and post it here.

    i appreciate you trying to help me and figure out what's going on since it seems like my story doesnt match up with others.

    ok, great. Here is one thing I noticed so far. MEGA CROP natural ph in your system was below normal, and Maxi was above normal. So, that means for MEGA CROP you have to add ph UP, and for Maxi you had to add PH DOWN to reach about 6. So, this might have something to do with it, since you are using different PH products with the two nutrients to balance it. So I will investigate more and see if I can find anything with ingredients in these different products.

    Also, when you test the PH later, is it possible there could be some fallout at the bottom of the res? So maybe over a few days, some of the nutrients fall out to the bottom, are you making sure to mix well before you run the later PH tests? Also, do you notice any fallout at the bottom accumulate over several days?

    so yours goes up a touch huh? and remind me again, are you on muni water or well water?

    now i'm confused. with maxi, i need ph down. with mega, i need pH up.

    i'm not using maxi and mega at the same time which is how i'm reading your answer.

    none whatsover even when i was using GH floranova which is thick as molasses

    nope, not at all. i run a small water pump set up as a waterfall which runs 24/7 and helps aerate and keep nutes well mixed

    I was just commenting, you use different PH adjuster products with the different products. I wonder if there could be something going on with your PH up, since you do not PH UP with Maxi. Just for a fun science experiment, if you have time and want to, take a bucket of water and add PH UP to it. Then mix well and test the PH. Then, check it in 3 days, and see if the PH has shifted, or stayed the same?

    i gotcha now. when you guys were testing, what brand(s) of ph up and down were you using?
    i can do that. and with no nutrients correct? ill do it with RO water since that is my preferred water source.

    yes, no nutrients. For PH UP we used Potassium Hydroxide, and PH DOWN Sulfuric Acid.

    i went to look at what GH uses but the labels on my bottles are impossible to read. i'll check their website.

    pH Up

    The premium solution maintaining and raise a nutrient's pH level. Base formulated using Potassium Hydroxide and Potassium Carbonate. Add a little at a time if your nutrient pH is too low in order to raise the pH to the proper level.

    pH Down

    The premium solution maintaining and lower a nutrient's pH level. Acid formulated using food grade Phosphoric acid. Just add a little at a time if your nutrient pH is too high in order to lower the pH to the proper level.

    nice, also, as a third experiment, you could mix up a small batch of MEGA CROP, add NO PH adjuster, then measure PH, and wait a few days and measure again. This should rule out PH as an issue :)

    You don't have to do all of these tests at once, consider it a fun science experiment :) MEGA CROP was designed to be stable PH, there shouldn't be reservoir drift. So I am a bit confused too about this issue!

    ok, experiment 1 under way. mason jar full of RO, pH was 5.19, no nutes. added 3 drops of pH UP by GH, pH is 9.68.

    meter was calibrated right before.

    will report in 48 hours about noon on saturday.

    I'd bet the potassium bicarbonate was being consumed by roots or other organisms. Makes sense then that the res pH would fall.

    i'm going to sanitize my res before i refill. maybe some bad bacteria in it but wouldn't other nutes show the same downward trend if so?

    i do drain to waste so no plants are in my res.

    Wonder if taking it higher then you normally would will make the experiment invalid?
