    COCO Impossible to properly PH!! Hate it...

    Re potting would be my last resort. I will try flushing daily with some ph offset and keep close monitor of any parameter change... So what do you use now? CNS17 too?? I have on hand some ingredients to make cns17 equal (Fatman's formula), but I doubt the validity of the Fatman's formula and...

    LOL!! I was blindly following the infamous "As#*d coco grow guide" from "THAT" forum (Is name calling allowed here??).... I knowwwww.

    COCO Impossible to properly PH!! Hate it...

    Sorry slightly out of topic guys.. But since we are here already, could you guys help me pinpoint what exactly is my problem.... I am leaning very heavy towards phosphorous lockout due to PH problem, slow growth and small fan leaves, but it might be magnesium problem too (older leaves affected...

    COCO Impossible to properly PH!! Hate it...

    I did exactly that plus run off ph too. Both are pretty damn close. Contrary to what poster from 'THAT' forum led me to believe, "dont worry about runoff PH, your going in PH is what matter".. It is all bollocks... Now I learnt, if your run off is high, then your actual ph is high too. Use...

    COCO Impossible to properly PH!! Hate it...

    I did exactly this and got this problem.... The suggestion to use dolomite was from the other forum with coco specific subforum and was posted by the most "expert" (Mehh) guy on coco in that forum... He swore by it..

    COCO Impossible to properly PH!! Hate it...

    High all, what is the most accurate way to ph coco? I am having a constant battle with ph ever since I mix my coco/perlite with dolomite lime at the rate of 1 tblsp/gal. Everybody said not to worry about run off ph, but when you flush your 2 gal media with almost 20 gal of RO water ph 5.8...

    Leaves dried up overnight!! HELP!! *PICS*

    I just re potted the three plants about 8 days ago. I mix the new coco perlite with 1tblsp/gal dolomite lime. I think this might be the culprit for my high ph.... My currently flowering plant without dolomite lime mix does not have any ph problem or any problem for that matter.... Some so called...

    Leaves dried up overnight!! HELP!! *PICS*

    OK... Only happening in older leaves, bronze color before completely brown out and die, crispy leaves tip, curling upward, veins remain green before dried up completely. These facts suggest magnesium deficiency... However I tested my runoff water... Even with 1/2 gal Ph 5.5 @500ppm epsom salt...

    Leaves dried up overnight!! HELP!! *PICS*

    Yes I believe that. I have another strain grown with exactly the same conditions and has doubled it size compared to the one on pics with no problem at all... Too bad I had to kill it last week due to it being a male.... What really confused me is the rate the problem occur...Overnight... I...

    Leaves dried up overnight!! HELP!! *PICS*

    Thanks for the link, but I read a lot before I commence my grow. I got many links with pictures for nutrient disorder. To my very limited practical knowledge and referring to all my bookmarked links, my problem looked like either magnesium or phosporous problem... i am just confused which one. I...

    Leaves dried up overnight!! HELP!! *PICS*

    I am going to try to reduce ppm since I don't see any difference in growth rate between 500-700 ppm anyway. I also suspected overfeeding at first, but the rest of the leaves are perfectly healthy with no tip burn or drooping at all. So I ruled out overfeeding.
