    Glad I could help mate. When I first started growing I had one nightmare grow after the other. My grow shop guru and the internet both said I did not need to bother with PH since I was using "organic nutes" (plenty of liquid mineral nute brands being called organic) (most of the tech sheets on these products do say to adjust PH)

    When I finally figured it out I decided to join the Talk hoping that I could help people with the same problem.

    My HM Digital PH pen holds PH better and longer than my bluelab which cost 3x more.

    Having buffering solution and checking often is crucial. I was told that recalibrating the pen reduces life. So I check in PH 7 first and then do the math to get accurate PH when checking the water or feed. I recalibrate about once a month only.

    Glad to have met you Icecalibur. Looking forward to seeing you grow soon! Cheers.

ID:	372819Thanks everyone, according to the water board in my area we are around 8.2 so after reading all these I’ve just ordered PH down and a PH pen, think i’ll Aim for 6.0 and see how they go, many thanks for the time taken from everyone, it’s my first ever grow so really appreciate it :-)

    Really nice to have met you too CD, really is something special about these forums..you get to meet such cool characters such as yourself to share opinions/ideas, general banter and pictures on a subject we all have in common

    Can't wait to share my grows..I literally can't wait to get back to my passion of growing cannabis

    Is this the pen you have mate?

    That's the one. With checking in buffering solution often I don't see the need for 2. I have a 2nd but it is put away until the current one breaks or cannot hold calibration.

    Nice plants! You should start a journal so we can all watch them progress.

    If my water was 5.8 or 7.2 maybe i would have been okay in organic. But my tap is 8.2 and it never worked for me.
    Hi mate. What’s do you use as ph down when growing organically?

    I'm growing organically and use regular pH up and down, ie potassium hydroxide/ phosphoric acid.
    I know they sell citric acid as an organic pH up, but really the hydrogen ions that lower pH or hydroxide ions that raise pH are the same regardless of the chemistry of the compound. The potassium in the regular pH liquids simply add to the potassium in the solution.

    My tap pH is 7 and a 25 litre bucket usually takes less than 1ml of pH up or down to adjust to where I like it, 6.5-7.
    Whilst the microherd do adjust pH in the soil, they find it easier to adjust down rather than up.
    When you do things right, people wont be sure you've done anything at all.

    I just finished my first grow and I never checked my pH during it, I did get a nasty colour on some of my leaves on one plant though, could have been a ph issue, who knows, I'm doing it now though, my tap water comes out at around 7.6, is that way too high? On my grow I'm doing now I lower it to 6.2,is that about right, I'm in coco?
