Coir said:One thing to remember is that you will need a lot more of it than Nitric and you will be adding similar amounts of sulfur to your feed just like you were adding phosphorus before which may or may not cause you more issues.
What numbers make an ideal nutrient profile?
For sulfuric, the auto parts store is the best place to get it. They do also have it at my local Lowes, in the plumbing section by the deep well pumps.JR Peters suggested buying sulfuric from an auto parts store. Any other suggestions or brands to purchase?
Yes, switching acids will change your nutrient profile. You will need to include the nutrient ppm that the acid you use adds to your nutrient profile. Nitric adds some nitrogen, sulfuric adds some sulfur while phosphoric adds alot of phosphorus. So changing acids changes the final nutrient profile.Quantrill it is interesting looking at the above post. I had calculated .66ml/g of AN Ph down so i was right on the money. But the problem was that it would not stabilize the ph over time. Changing to nitric or sulfuric will change my nutrient profile? How i do not understand this yet? Also will these two stabilize the ph and if so why?
Nitric acid doesn't drop the ph as much as sulfuric will. Either way Nitric drops my alkalinity to 55 and sulfiric to 54 with a target ph of 6.0.
