    My tap water(well water) is 7.0 and I have to use PH UP with my Foxfarm Nutes for flower as they drop the PH to around 5.
    But when I use my Tapwater just for watering I have been adding a few drops of PH Down to lower it from 7 to around 6.7.
    Is This NOT a good thing to be doing as It has been worrying me if I am doing the right thing.

    Oops, your right irydyum, I wonder how much I smoked last night to get that math!

    Actually, I've been using FF for a couple of years, and regularly test my ph pen against calibrating solution. I'm confident enough with my numbers to stand by 'em, give or take a .05 range either way for different batches, age of product, different testing methods...

    What do you use to test your ph? FF bringing it down to 6.5 I could understand, but 5.0 is unthinkable under normal dilutions.

    From experience...If my tapwater ws 7.0 and I used Fox Farms, I doubt I would feel a need to adjust the water one way nor the other, unless additives added to this ph shift. Stuff like Botanicare Sweet and CalMag Plus are very acidic, molasses is slightly acidic...and I'd likely account for that in some way. But the FF line itself should be fine with tapwater at 7.0 ph.

    I have 2 Milwalke PH600 pens and have cal soultion. I use about 2tsp Tiger Bloom and 1 TBl spoon Big Bloom to gallon of 7.0 water and it was like PH 4.9 before I added about a good tsp+ of GH PH UP just to bring it up . I will start watering without adding PH Down from now on.My plants are outside 1 Hermey and 1 nice 5'+ Female and both look healthy and sooo close to harvest.
    Thanks for the help as always.

    Rusty,

    The little bastards look like gnats or little flies. They are dancing in my soil and prancing up and down the main stem of my two mothers.

    Have used pH Up on my three daughters in an attempt to raise the pH of the run-off from the current 6.0.

    My two mothers have a runn-off of 8.0. Have been watering them with RO water with a pH of 6.0. Should I be using pH down on these two or would I be better off flushing with the straight RO water at 6.0?

    Thank you again!

    I hope you mean adding pH Up to the water, and not adding it to the soil. Reads a little funny, and makes a MONSTER difference.

    No, I added the pH Up to the RO water I use, which has a pH of 6.0.

    :thumbsup:

    Get some Raid, (strips) and clean-up any leaf litter in the pots. :thumbsup:

    Not too sure about the use of phUp, but am curious how long it lasts in the soil. Did you use it previously with the mothers'? If so, it might still be raising the ph on ya. I would flush once (2:1 water:volume) with properly ph'd water, (6.3 to 6.7ish) and go from there. I try to never purposefully raise or lower the ph out-of-range. Sometimes necessary, but not recommended.

    Good luck.
