PH adjustment

Hey folks, Im wondering what can I use to adjust the PH effectively in my RO water without killing healthy microbes and bacteria in my soil? My RO comes out at 5.5 PH which is super nice, but once I add my nutrients and what not, it drops to 4.3-4.5 PH. Any suggestions?

Are you just being a cunt, or are you just too stupid from banging your head off the wall for too long? My question is valid. Its called organic agriculture. PH up and down kill healthy microbes that stabilize the soil. I could also make a compost tea but its a lot of work and the buffer in the soil isn't going to compensate that much.

Nutrients contain ph buffers that typically drop the ph of the water you are adding. Runoff is not an accurate representation of the actual ph of the root zone nor is checking ph of the water/nute solution you are adding. A soil ph meter would tell you if your ph was out of range & the only way to adjust it then is to use additives in the soil like lime, oyster shell flour, or peat moss.

Are you sure your ph is out of range in the first place? If your plants are not deficient & you use a bagged soil chances are your ph is just fine. Ph the soil not the water when growing in soil & use those nutes sparingly because as you can see they do affect ph when they are present in the dirt & can cause more issues than they solve if used improperly. I say go totally organic & toss them nutes out. Then your water only mix will stay in proper ph range with literally zero effort.

How am I suppose to feed the plants then? Plus the soil is already done. Its basic organic Promix. Nutrients are necessary to obtain proper growth and yields.

This sounds like a thread that should be in General Indoor Not Organics. What "organic" nutrients are you using? The point of Real "organic" soil is so you do Not have to add nutrients when watering--at least in my opinion that's the case--but if you are trying to raise your pH then just add some Lime to your water. Boom. Organic. Done. No microbes killed. To lower pH add some Real Raw Apple Cider Vinegar.

But again if you're using nutes, then adding a pH balance is Not going to a/effect your "microbes"; what are you using?

compost teas aren't a lot of work man.
I'd recommend a different media to grow in, if you truly want to go organic, but testing the ph after you add nutrients is a fools errand, 95% of organic nutrients create acidic conditions. Temporarily.
you want to build a soil that promotes more of a neutral ph, concentrating on various liming amendments, like crab or shrimp meal, oyster shells and oyster flour, using more compost base as opposed to the acidic nature of peat, etc.
what I would do is assemble a soil on your own, all the information is here, and on many other grow sites. Make the soil now, and by the time you are ready for the next run it'll be cycled and ready.

You can use coca cola or coffee for a ph down, antacids or milk of magnesia for ph up. As long as you put in enough to bring the ph to the goldilocks zone the microbes won't mind. Don't expect the ph for the soil to stay at the adjusted level for long, though. But what about that 5.5 RO? Are you sure that's a correct reading? Have you calibrated your pH meter?
