    Not all grows are perfect...

    I might be wrong but it looks like a potassium deficiency.

    I double check my ph and it is 6.4 so it's fine

    Temp in the "grow room" at 26.1C

    HR at 45%

    Soil is close to moist from what I see on my meter

    Only 3 of my Kali China are having this issue the rest are just fine.

    Tomorrow I will begin a flush on those 3 girls, no feeding for a few days.

    If I recalled with the KC I had some issues also last year.

    If needed I might feed them with my own homemade potassium made with banana peel.

    Only Farmbuck can make a sick leaf look pretty. With the leaf stems being dark it could also be phosphorus. Do the leaves that are not yellowing look at all blueish looking?

      MeEasy no, not at all it's just that strain but just the bottom leaves. My Kali 47 and my Mazar Kush are fine and dandy. Like I was saying the first time I grew them I had some problems but then Ace suggest to use in moderation the nutrients on them. So why I'm thinking of flushing them.

      I had a problem a while back and thought it was potassium but ended up phosphorus and my brother said to look for a blueish tint in the health leaves to tell the difference in the two deficiencies. Bananas is the way to go or at least it sounds good to me 👍

    Morning Farmbuck it's my bottom leaf on my autos a good flush " re boot " works wonders.

      Yeah, I get it. I have four plants each a different strain. Everything about how I have worked with them is identical. One, a Critical Poison persists in showing a nutrient lockout problem. I have totally flushed it twice already. Sometimes you get the bear and sometimes the bear gets you.

        Ain't that the truth OldManGrower. It's winter an this is when my issues with indoor grows show up.

      It's funny how some strains reacted differently lollllll They are in the same room, the same temperature, the same humidity, the same soil, the same nutrients and the same amount of water. It's not I'm using extreme training but then I wonder if it's not my PRO-MIX that I'm using ? Can't be the other strains are happy..! Also winter and the dry air in the room may be the culprit hey

        I just performed a Hail-Mary Jane. Even after two flushing's, my Critical Poison was still showing what I can only call a mineral lockout. So, In desperation, I removed the plant from the soil, rinsed the root ball with water to remove as much soil as possible and repotted it with new soil in a new pot. If that doesn't work, I'm going to most likely lose the plant. Pity, its a really nice plant.

          I’d suggest its phosphorus deficiency that is also creating some calcium issues.

          26C and 45%rh is a high VPD which will lead to nutrient issues. Not sure what’s easier for you to control for temp and humidity, but you need to up the Rh to around 60% for that temp, or lower your temp to 18C for that humidity level.

          Are they in flowering stage?

          Cheers

          There are 3 things you must check everyday when growing in hydro:
          1) Water level (How much h2o is she drinking in 24hrs)
          2) pH level (change over 24hrs)
          3) ppm/EC level (How much food is she eating in 24hrs)

            Flipped them two days ago. My humidity is at 28% and temp is about 73F.

            Wow 😳 what a persnickety strain. Hopefully they recover.

            They are doing much better this morning, temp is at 25C + but not above 26C. I'll remove the remaining bottom yellow leaves today.

          My sick Kali China are doing better.

          The Potassium Deficiency really caused me trouble. I was in deep for the issue was resolved and it occurred in the late flowering stage... Now I have a little cheat sheet with a few of the yellowing causes.
