Just got my ph tester today. I tested the soil my plant is in and it read at about 8.6ph which is WAY over what I've read the target area is. I've had some water sitting out for about a day and a half now so I plan on flushing tonight! I hope I do this right! I could not find anywhere to get "Earth Juice Natural" which I read was a very good ph up and ph down. Does anyone know of a good product to buy that is found at a common store? I'm working with walmart, menards, home depot, lowes...those are pretty much it. If its something I need to order from online could you please let me know the website? Thanks!
