When you get a chance I would love to read the article if you can find it.So just for the sake of OP
in soil when using bottled synthetic nutes your range is 6.0-7.0
during veg you stay on the low end
ideally during veg 6.2-6.3
during flower you run the higher range
ideally during flower 6.5-6.6
in a fully organic non chlorinated water soil grow you want
in the range of 6.0-7.0
but the caveat is that it doesnt really matter if your water is higher because the microbes in your soil will buffer and feed the plant. my well water i use on my outdoor plants comes straight out if the hose at 8.3 ph.
I have never phed water for my organic soil grow
but you cant have overly acidic water if you arent phing during full organic
most tap waters are going to be more neutral not acidic.
i dont think you could drink water that acidic so you wouldnt have it for plants. most tap is high ph not low
if its that low out of a well, you shouldnt drink or use it for plants i would think
during veg 5.7-5.8
during flower 6.0-6.2
i havent had any leaf issues since i started watering my cocopeat at these ph’s
if you want i can find the article that explains the actual reasoning behind how a cannabis plant uses nutes in their medium and either makes the medium more acidic or more neutral during different parts of its life
cannabis plants make ph go up during veg, this is the reason you go on the low range of the mediums PH during veg.
during flower the medium becomes more acidic, the reason you go on the high end of ph during flower.
a medium is always going one way or another, the ph of the medium is constantly going one way or the other, so you feed on a lower or higher end so the plant takes in the nutes it needs while it goes up or down on the ph range.
not sure if that makes sense, but thats how it works for me. i would bet money it would work for you @SQl2kGuy
I read this once tonight ... and I will digest it tomorrow. Actually, I will probably copy it into my Lessons Learned section and give you credit for writing it.
I am 100% about science and engineering ... and I'm really trying to understand what is happening.
I am sure I could grow cannabis using the patterns here ... but I want to understand the details whenever possible.
Thanks for getting technical ... I really appreciate it!
PS ... what does OP mean in "So just for the sake of OP"
