    The fact she's really the only one remaining with these issues could potentially mean she's just a sensitive one..but always best to have as many eyes over issues as possible.

    Just to add, she does look healthy despite the banding

    The issue in your first post as I said before is in my opinion just splash burn.
    Cheers mate have filled it out again, I’m not sure what’s going on with her at the minute but she’s stressing me right out. On the other hand, it’s only another week until I switch to flower so whoop... just hope she manages without a spray until I can get hold of the calmag

    However you have something else going...Your either not feeding enough and or the pH is off.



    If you are still using this ratio above 0.5ml of A&B is nowhere near enough for the size of your plant/s and the stage of growth your at...Thus the plant/s will be deficient in the essential NPK's and micro elements they require to maintain healthy growth...

    I was using 0.5 mate, up to 0.75 now. Should I start increasing it to meet a schedule?

    If you ain't got an Ec meter feed 1.5 ml of A&B...If your measuring the Ec then go 0.6 to 0.7 above your base...pH @ 5.8 plenty of runoff...


    Regards BL

    Cheers mate, about to feed em all now. I got underpaid this month, which caught me out a bit so I couldn’t manage to get a meter. Next payday should be able to grab one
