Can someone answer some questions on a organic pH down?

I have a few questions on Ph down substances and if anyone could clear them up for me i would greatly appreciate it, and this forum i believe is the most credible place to ask.
1. I currently use pH down from advanced nutrients, which as we all know is simply phosphoric acid. Im having to use a 1/4 tsp per gallon to get my water down to 6.0 and im wondering if adding that much phosphoric acid to the water could hurt my beneficial bacteria and fungus in the soil?
2. I read that a good organic pH down is Bio-Nova's Citric Acid. But upon reading into the info posted by the company that makes it, they recommend using it only as a bi-weekly supplement and should not be used in conjunction with fertilizer. Does anyone use this product or know if it is safe to use as a regular pH adjuster?
3. Lastly, in the event that the Bio-Nova is no good as a regular pH adjuster, could anyone recommend what they use. Earth Juice perhaps?
I know its a big question for such a simple thing, so thank you for any help.

I also use AN PH Down.

Organic Ph down is basically a much less acidic acid and you will find if you mix nutes in advance in DOES NOT hold the adjusted level for as long as Phosphoric acid.
Yes Organic is better for the soil and plant over Phosphoric acid, but in small amounts it gives no detrimental effects, it is only if you are having to adjust a significant amount (use alot) that you should worry.
I use hydro and found that I was using FAR MORE organic Ph down and on a more regular basis compared to general ph down.
This was not cost efficient at all and was also much more time consuming.
Organic or not...... too much is a bad thing.

Damn man, their ph products scare the shit out of me. Those bottles are frickin heavy, and the fact that you aren't supposed to store their up and down next to each other just scares me away. That can't be good. I use EJ organic up/down when I really need it, but I rarely have to use either.

I use citric acid for PH down , I dont have to knock it down much and it's cheap .

I use the natural Earth Juice up - down!!
