Best ph Up/Down Solution? Are the ones with multiple ingredients (buffers) better?

I read elsewhere today that GH I believe it was.. uses 2 ingredients in either their ph Up or Down... Don't recall which it was...

No one have any details on this? Was planning on taking a drive down to the hydro shop that has Mad Farmer locally if it sounds like a 3-part formulation is the way to go...

i have used gh for years and got a free sample of mad farmer a couple months ago to try. i just ordered a new gallon of gh last week. not worth the difference.

I have to wonder if the dyes are anything worth really sweating or not... From a purity stand-point I get it... but... does it actually have any effect on the end-product whatsover?

"Prepare your nutrient solution as usual, at the end, add 5g of citric acid for 500 liters of solution (this will acidify the pH of your solution a lot). Now, take back the pH to the value you want (5.8 to 6.2) by adding potassium carbonate. "

I'm switching to this once I use up some more of the sulfuric acid and sodium hydroxide I have now. Save yourself some $ by not paying for off the shelf products. $20 of each will make a couple dozen gallons.

Ideally you want to use nitric acid for a pH down during veg, and phosphoric acid for pH down during flower.
a good pH up would be potassium hydroxide.

Does it REALLY matter? nope. You won't be able to tell any difference in your finished product. Any commercial pH adjuster is just fine. Dyes make no difference either way.

You eat hundreds of dyes and dye compounds daily.
