What is your pH that you're adjusting from? What's your soil mix? Why do you feel the need to adjust your pH anyway?
The microbes will buffer your pH in your soil naturally for you. I don't even bother with a pH meter, and for the most part in an organic system it's unnecessary. (though I'm sure I'll get eaten alive for this). :-)
Buddy,
How much Roots organic in relation to the Denali Humus and EWC? Are you mixing in additional perlite/vermiculite/pumice?
I've heard EJ can really swing the pH of a nutrient solution, and I personally haven't used it. The forum I usually post on has a couple hundred post thread on the subject and it seems that many people do adjust it or bubble it prior to application.
Soil is amazing stuff, and the microlife can buffer quite a bit. I realize that you don't want to experiment on your plants though. The other forum I mentioned also has a thread on pH and organics. The basic concept though is that if you're applying organic nutrients (in proper concentrations) into an organic system, then you don't need to worry about pH. The plant is actually in control based on the exudates it's putting out into the rhizosphere, which in turn determines the microbes that will be most successful around the root zone. These microbes will create an environment that is properly balanced for the plant to be most healthy.
Glad to hear you've read "Teaming with Microbes." Jeff is an old friend of mine and a great speaker if you ever get the chance to hear him talk in person! :)
Thats for 1 bag of Roots. I mix 30% #4 perlite...the big stuff.
I'll be honest, I'm a bit ignorant on commercial soil mixes. I have heard a lot of people complaining that the quality of Roots soils have gone way down and people don't like using them. I'm not sure how big the bag is, but I'd have a minimum of 20% EWC or high quality compost in that mix.
Perlite is okay, but I prefer pumice because it doesn't float to the surface and they're may be some cation or mineral exchange over time, while perlite is totally inert.
Hope that helps!

I usually end up in the high 3.xx's ph. After 6 hrs bubbling yesterday it jumped a tenth or two.
TIA
The Earth Juice is causing the 3.XX pH, right? I've heard if you bubble it for a while, the pH rises? That seems like the easiest fix to me....
Doesn't rise for me very much.
I am curious about the relationship between ph and organic soil. How much can the soil (good micro filled soil) buffer?
I see organic soil guys saying they dont even OWN a ph pen. Is that to say that feeding 3.xx or 9.xx is ok in "good" soil?
I just cant see it. But thats why I am trying to learn and ask questions.
I'll be honest, I don't pH anything. Most of the growers I know don't bother either. I'm not using EJ either though, I focus on the soil and would only feed during the cycle with ACT, seaweed, humic acid (Tera Vita's LC-10+7), and maybe some light molasses or fish hydrolysate (not emulsion, and not with the ACT).
Hard to say exactly what pH conditions the soil is able to handle. This is not a cut and dry answer because of the varying microbial life and conditions in very soil mix. I think people over emphasize the need to pH in general. However, I do know that my tap water is fairly close to neutral, and I'm not adding anything with a crazy pH either.
