    Ok bare with me im new .
    I have a bubba kush plant in flower 3 weeks was seeing issues a week in & talked to our local shop guy and he says I was over ferting so I cut back as he recommended. I am in DWC using air stones I keep my water temp at 68, pic below shows what he said was over ferting. I was mixing as the label called for and after mixing I was 720 ppm he said I should be no higher than 480 as my water out of tap is 80 ppm sorry I had no ec info still not getting that part. I change my water once a week check my ph once daily I have changed water twice since I lowered my mix & now I have a new issue of yellowing, pic's included
    Indoor Tent with fans, Led light
    Room temp average 70 night 75-80 day
    Normal humidity for my room 44 give or take
    As of tonight's check my numbers are.
    PPM 411
    For EC my meter reads 0822 us/cm , im still lost on this .
    PH 5.6
    If i missed any needed info or my post it to much please let me know.
    I am using Canna Aqua Flores & I add some cal mag pic included
    Any help would be greatly appreciated !

    PH of 5.6 is acceptable, but it's right on the cusp of being too low and making certian nutrients inaccessible. Try bringing it up to 5.9-6.0 and see if that helps...it is definitely a nutrient related issue, whether or not it's related to PH idk, but its my best guess...you haven't had your LED's really close to the canopy have ya?
    *EDIT* Did they do this before, or after lowering your ppm's as your local hydro guy recommended?

    80 out of the tap is fine. PPM should be around 600 easy at your stage of flower. Watch the PPM daily for rise or fall.

    I see no tip burn. Are you giving Micros that include iron? Most include sulfur but check.

    When you increase your PPM go low or no nitrogen. Cal mag should have that covered.

    Just seems low to have burn but we read the plants and adjust using the meters instead of the reverse.
