Hey buddy, you can use lemon juice(I use the one in the bottle shaped like a lemon) for a PH down. Id take out a gallon and add a few drops, test it and then go from there. If you got any questions just let me know~!

It was at about 8.0 earlier today so I went out trying to find some phosphoric acid or nitric acid to no avail. I fucking hate lowes and home depot they can suck my ass. I have never been able to find anything I want there. I know I should have bought some ph adjusters when I bought my nutes at the hydro store, but now it is too late since the hydro store is like 40 Rating: 5
