HELP! New Grower - PH Concern

[ForMyHealth]

The Up/Low Ph is only burning the fuck out of my poor plants. The only girl looks so sad, and about 80% of her leaves are now burnt. She is still young and I’d like to save her, made a post about it earlier but didn’t get much help, so can anyone tell me how else can I adjust pH of water ?
when I search online all I’m really pulling up is the ph up/down bullshit

I didn't see your earlier post. Can you post photos of your plant. Preferably detailed photos of the effected spots. Be sure to post as much info as possible about your grow. Strain, substrate, lights, watering practices, feeding, ph, lighting and so on.
Typically burnt leaves are a result of too much nutrients but without any info of pics I can't be of much help..
Baking soda can be used to raise ph and lemon juice to lower.

The pH Up and Down use potassium and phosphorus ions to change the pH of the solution. Both of those elements can be absorbed by the plant as nutrition. That's the reason just about all of us use them. It sounds like the EC of whatever you're growing in may be too high. Using pH Up and Down will tend to raise the EC a bit, but not a helluva lot. No matter what you grow in, make sure your pH pen is working properly and you have an old fashioned method for backup - like the pH test fluid GH sells alongside pH Up/Down. I've had a pH pen go crazy on me before and it set me back about three weeks once. A good EC/TDS meter is a must too. I'd suggest a water change if you're in hydro, followed by about half the nutes the maker calls for, then pH Up/Down as needed. If in coco, pH adjust some plain water and flush the plant with it then let it sit until it's thirsty again.

There are many things one can use to PH with, acids make the soil acidic, and alkaline's make the soil alkaline. Can you give more details on what you need/want?
Lemons can be use for acid, vitamin C as well, bananas are acidic. These will get you a PH down (also kills chloramine and chlorine in tap water)
Potash, wood ash will get a PH up, but what do you need?

Why are you convinced pH is your issue? Lots of reasons leaves can look burnt. It's very difficult for anyone to advise you without more data on how you're growing, what nutrients you're using, etc. It may not be a pH issue at all and frankly many people use the BS products you're referring to quite successfully.
