Looking for ways to lower my ph. The ph of my water is about 5.5 to 6 but after adding ferts to it especially 0-0-25 it gets jacked up to the 7 to 9 range. Any ideas on lowering it besides using ph down.

Citric acid might be a possibility.

Just how much 0-0-25 are you adding that it swings the pH that much?

May try adding pH down to the 0-0-25 before adding it to the mix.

Andy I add 1 cup of 0-0-25. I know some other ferts increase the ph as well but not like the 0-0-25. So what I was doing is putting equal amounts of 0-0-25 and ph down into my mixing bucket but when adding the ph down the mix would start to bubble aggressively for a few seconds maybe thats ok but I questioned weather it was or not.

If I understand correctly, you're checking pH in the concentrate bucket? Have you checked to see what the final pH was that you're irrigating with, or is that where it's off?

No I check the ph after the injector.

If it bubbles I would guess your destroying something in the mix. There are steps to take to mix chemicals together

The Basics Of Mixing Plant Nutrients
While it may seem like common sense, its important to note that before you add in any type of nutrients, you need to have a water source. Do not try and mix nutrients together without water as a diluent.

This will cause all sorts of chemical reactions among the nutrients, and result in settling/fall out. Your plants won’t get the proper nutrient ratios.

Your PH Down (acid) is reacting with the potassium carbonate in the solution and producing carbon dioxide gas (bubbles). What you're left with in solution is potassium chloride. Unless your drip tape is clogging from the 0-0-25 coming out of solution I would not bother lowering the PH.
