look at the ingredientsAppreciate it guys. I understood some of that.I'm back to using House & Garden, years back they used to recommend letting the part A gurgle for 10 mins or so, one of their reps told me they dropped that but I still do it for OCD reasons. I also put my calmag in early too for some magical reason I don't understand.
It sounds like it's normalish I always reset the ph if I use it the next day. I mostly wanted to make sure that my brand of ph up/down wasn't artificially or just temporarily doing its job.
Mad Farmer Get Downlook at the ingredients
Ph up is good. Ph down I just use 85% phosphoric acidMad Farmer Get Down
phosphoric acid
citric acid
ammonium sulfate
Mad Farmer Get Up
potassium carbonate
potassium silicate
potassium hydroxide
Citric acid is a weak acid and is used as a carbonate buffer in pH down.Ph up is good. Ph down I just use 85% phosphoric acid
All acid is used to buffer carbonate in ph down. I agree citric acid is weak and a poor choice for hydro. It also very cheap and why I believe they use it as a filler. Straight phosphoric or sulfuric acid is much better. At higher concentrations like I use at 85% I suggest diluting 10-1 before useCitric acid is a weak acid and is used as a carbonate buffer in pH down.

What's the advantage? I can see to spread the sources out but can't see any functional benefit other than that.I have read that including multiple forms of acid is better ph down.

I can't see stability. Unless they are trying to claim that nutrient uptake may interfere with source of acid but IME that holds no water and may be just another marketing gimmick to fill with cheaper acid. Source should be taken into account but if you have the right alkalinity to start with you should not need so much that it interferes. If any blend I would do sulfuric and phosphoric. Nitric and citric would have very specific uses for a very dialed in grow. Citric imo should never be used unless your not getting enough drift but that's a very specific use.I dont know but most of the ph adjuster brands use multiple sources. And when i learned about it i read that.
Maybe better stability? I would have to re search for answers.

Doesn't work that way afaik. I don't believe one acid will affect the stability of another.I disagree. Different acids have different composition and break down at different rates. Maybe longer lasting stability from multiple sources.
But im just guessing still.

@cemchris may have a good handle on this. To my knowledge atleast it doesn't affect stability but rather a blend would be a cost cutting solution while still providing an adequate product.
The only way I can see any impact is nutrient uptake like stretch where the plants can be a phosphorus hog.
Yes that what I mean citric breaks down in about 12hrs IME in a well aerated system. I have never seen a hydro grower with the issue of ph not drifting but I have seen numerous ph drifting to much (instability) so for our use we don't have the issue of short and long term. Just the issue of ph drifting to fast. Which will be 1 of 2 things. Weak acid ph down like citric... Or inadequate buffer to start with creating stability issues. Because of lack of buffering. Basically you can't add enough acid to keep it stable without a ph crash or extremely low phNot one acid stabilizing another. Different acids affecting alkalinity differently. Like calcitic and dolomite lime for long and short term ph control.
