    HELP! Blueberry need your help

    Hello growers!

    As I told you in previous posts I grow Blueberry fem.

    Here are some info:

    Strain: ​​​​ Blueberry
    Week 3 of flowering
    Growlight: Viperspectra 450W
    Growing medium: Soil
    Temp/humidity: 27 (Celsius)/50
    nutrients: General hydroponic flora trio

    PH: 8.0

    As I mentioned PH is hight, so that causes some deficiencies.
    ​​​​​Maybe manganese or magnesium deficiency (or both together)

    brown dots and yellowing started from bottom and moving up at the top.
    However buds are growing well.

    First thing I did was flush. Unfortunately I dont have such great thing like GH ph up/down, so I use lemon powder which is not best option, but does something.

    I flushed with Ph'ed (6.5) water, 3 times more liters that my pot is. But PH is still 8.0

    In my opinion problem is in lemon powder which is not such strong to maintain low PH. Or maybe I need more amount...

    ​​​​​​​Anyway would be glad to hear your advises.

    P.S. I know that best option is to buy PH up/down but it needs about 2 weeks for product to arrive in my country, So I have to do something before.

    One more option I think about is that my friend who is also grower uses "advcanced nutrients" which got PH perfect technology, but I dont wont to mix GH with other brand nutrients.

    You might try using just distilled water, or rain water. Do you have a rain barrel? I am sure that is available in your locale. Distilled probably a bit pricey, but what the hell. Not sure what that looks like, but I think you'll make it to harvest.

      No the seeds are from my local online shop. And what you mean about distilled what, does it have lower ph?

      Yes usually 7, but better than 8.

    IMHO:
    Strongly suggest for your future PH down at least and a BlueLab pH tester. Expensive but worth dry cent.
    In just looking at your images...I would suspect your soil is too wet?
    Lastly: most pro growers still test theirpH perfect regardless since if it were true we would ALL be using their brand.
    Again...Just my opinion.

      Tika

      ​​​​​​Pics are right after the flush, so that's why soil looks so wet.

      I was reading that vinegar is more stable than lemom powder.
      But what is best, to wait until soil dries out or water with vinegar'ed water tomorrow.

        i think she might be talking about the leaf coloration. Tika?

      I was with Tika. Root problems or fungus knats from the medium being too moist would be my guess. The only times I've had symptoms that look like that, its always been 1 or the 2. Only on youngins tho...what size pot are you using? Maybe rootbound? Can't take nutes and water like its supposed to? Hope you figure it out!

        Morning Zaxar, if you can't get ph up-down, use whatever you have to make sure the ph is where it supposed to be when you water.
        Next time start with good soil an you want have these problems.
        You need a super flush, where it lowers the soil ph, in one try.
        Cfls for a week or two
        315lec for everything else
        Dug up Ms.topsoil, with perlite added
        36x36x63 inch tent.

            Try flushing with 6.0water. It's gonna take more than 3 times pot size .

          You don't want to make drastic changes. Do it gradually. A couple weeks ago my wife cleaned her fish bowl with vinegar, and poor fishy fishy was found floating on the surface the next day.

            As I mentioned I flushed her last time, so maybe plant will be stressed with 2 flushes. So maybe just water with 6.0 ph water will be better option?

                Watered today with 6.0 ph water, runoff was 8.0 again...
                Than I added more viegar to water and continued this until final runoff became 6.5

                  Friends I need your advice.

                  after a lot of readings I finally figured out that my blueberry got magnesium deficiency.

                  Leaves starting to yellow from bottom and moving up, with brown dead spots.

                  after flush as I said ph is 6.5. But leaves continue to yellow. I think it needs about week to recover.

                  Today I was reading that you can apply
                  ​​Epsom salt via foliar feeding, for quick results as it contains magnesium.

                  ​​​​however I got GH cal/mag and thinking about applying it on leaves. But I don't know dosage. Also I'm not sure if it is safe to aply foliar feeding during flowering, as it can harm buds.

                  would be glad to hear your advises.

                    Don’t foliar spray it. Make a solution and water as normal with it. Calmag will lower the ph of the solution. Water with ph 6 until runoff is ph 6.5 then keep it at 6.5.

                  Morning Zaxar, is there anyway you can take a few pictures in natural light,? it's hard to see in yours with the light on. Then maybe someone might be able to help you.
