    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.
    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.

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

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

    Well Ace claim the Kali China is a indica dominant, 70% indica and 30% sativa. She is a cross between a Kali Mist (mostly sativa) and China Yunnan (mostly indica). Now I remember she was a finicky eater from last year and also she need 25C during veg and 3 wks in flowering follow 20C till harvest. Not an easy strain to control. I have a Kali 47 a cross between again a Kali Mist and AK-47 and they are doing just fine. Same goes for my Mazar Kush no issue.

    The 26C and 45% is during "light on" for 18 hrs but once the lights is off t's 18C to 19C and the HR is close to 60%, Temp I'm able to control since I set the thermostat to 20C and since is dryer here during winter I could buy a humidifier for the veg stage. Anyway it's just 3 plants out of 21.

    But thank you so much for your input YYC.

    Cheers from Canada

    Make a note in your grow journal that they are very hungry for “something” during late veg 👍 We all know that different strains (especially hybrid strains) don’t follow the “rules” of growing like the older land race strains.

    Any idea what the ratios of indica to sativa are for that strain?

    Nope YY I'm in my 7 weeks of veg. It's just the Kali China that have the deficiency, the other strains are just fine. You know I was thinking the same but last Friday they had their Alaska fish but only half of the dosage and today some Cal-Mag so I'll see in a few days. Like I was saying just the KC but the old and bottom leaves.

    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

    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.
