yes it's true but I would only use it in an emergency. Lemon juice is good. Phosphoric acid is ideal, as it is also a major nutrient required for growing (the P in NPK) Alaska Mor Bloom fertilizer (0-10-10) is Phosphoric Acid & Potassium Chloride.
yes you can. as it breaks down it is used by the plant.
i know this is a old thread but for any one who comes across this it is 1/4 tsp vinegar per half gallon for 1 point -PH so if you have say a ph of 7.5 and add 1/4 tsp vinegar you will be at 6.5I heard use a couple of drops of vinegar to a gal. of H2O, This should lower city tap water which is in the range of (6.8 - 8.0 pH) now don't quote me on this range or formula sine it's speculation, but almost correct. 2-4 drops of Vinegar *regardless to brand and type* preferably apple cider vinegar is okay, regular clear vinegar is good since simple is best at times, i heard wine vinegars are to avoid. A few drops will lower it to 6.5 pH which is good but if you have hard water or it's reaching 8 i say dump it and get some drinking water in a container let it air out for a few days add a few drops of vinegar you should be fine
What's bad advice? Using apple cider vinegar? That's all I ever use and have no issues. Are you using city water or well water? If city water are you gassing off the chlorine? What do your plants look like?
You are right, this is an old thread, even older than your membership....yet the only 2 posts you made were today on this very old thread.
If your in good soil you don’t even need to worry with ph. Hell most good coco blends have buffers the correct the ph.
First, what medium are you growing in?
