    Default Leaf problems

    Im getting a lot of this starting on my leafs at around 3 weeks of flowering. Femanized skunk and skittles not sure witch plant it is i forgot to label them. My ph is about 9 and my ec reading has been about 1300. My freinds been watching them for me and let me know that therr all starting to do this. Iv put it down to the ph being to high and the ec being out by abput 200. Just checking if im right in those resdings causing those issues

    That ph is way too high. Whatever way you grow. You need that down.

    Reduce your PH to 5.8

    ....EC doesn't go as high as 1300

    I would think it’s a cheap meter and that would be 1.3 i would think. M_C. Never seen a ph that high before.

    TDS? PPM? Possibly... but it's not EC

    My tap water is PH 7.8 & I think 9 is the top end of acceptable?

    When i was using the wilmas i set ph to around 5.7-5.8, it usually raises after a day or two then just re-adjust down again. As for ec different strains, phenotypes, enviroment, background ec etc... all effect what ec you use. Better to keep it on the lower side though as too much will cause nutrient lock outs and tip burn. Check out my wilma diary "underground wonder woman" or something like that i pull just over 40oz of 4 plants, might be some tips and advice on feeding.

    I'd be checking under the leaves with a loupe after seeing the last picture...looks like two different problems to me.
    I know a girl who thinks of ghosts,
    She'll make ya breakfast, she'll make ya toast,
    But she don't use butter, and she don't use cheese,
    She don't use jelly, or any of these,
    She uses Vaseline.

    what is the low side re the ec? also I was getting curling up on the leaves.from this forum I've been advised it may be light/heat stress.also my humidity is real low,between 20% and 32%.i'm awaiting a humidifier next few days so hopefully that'll help.i've now turned lights on 20/4 cycle.

    I have a high background ec, I keep my ec in veg around 1-1.2 (maby upto 1.4 depending what products im using) usually, let the plants tell you what they want, if they start yellowing in the new growth higher it slightly. Depends how your leafs are curling mate edges curling up usually is heat stress, curling down can be a few different things like over/underwatering and overfeeding. get the humidifier on try raise humidity up during veg and early flower then after 2nd or 3rd week of flower remove humidifer.
