    Is that the PH of your run-off if growing in soil?

    I'm getting 5.6 runoff and have yellowing leaves which i assume is "N" lockout so if I water with plain tapwater at PH 7.4 until the run off rises to around PH 6.5 next time I feed should the plant be able to take up the "N"?

    You need to know th ph of your tapwater 1st & use that to water, then test the ph of the run off & see how much it goes down by. Then adjust your tap water accordingly, so say u put 7.5 in & u get a run off of 7.0 the difference is .5. You then want to ph down your tapwater to 7.3 so hopefully then your run off will be 6.8.
    Thats my understanding of it anyway, currently doing it, so far so good. My last grow was very nearly a right off untill i started to ph the water.

    I asked a question last week as to what the ph of my water should be if im using soil and was led to belive it was meant to be 6.8.

    Looking at this chart it seems it should be 6.5?

    Could anybody assist as to which I should be using?

    I've always been told that the ideal pH for soil is 6.5. That being said, my run-off is 6.8 and the plants are doing just fine.

    sorry didnt want to start a new thread about this so i though i would come here... is there a point of no return when your plant has sufferd fron high ph like 7.5-8? i had it in for about 2 weeks then corrected it and nothing changed it just seemed to keep getting worse.

    Take a look at the plant in my grow diary as i may have a similar problem. Are your leaves yellow and browning from the bottom of the plant up, leaves wilted and slow growth. If your symptoms match mine im afraid the outlook may be bleak. i have resorted to placing the bare root ball in my nft to get my girl out of unsuitable compost as a last resort to save her. hope this helps
