Here's one for the experts. Depending on what happens in the next few days I may have to flush 5 plants. The standard from what I read is 3x the amount of water of the gallon you are using. I am using 3 gallon pots so that would be 9 gallons x 5 plants = 45 gallons. I would need to borrow a truck to get that much water home. I have always watered them with RO water from the store in 5 gallon increments. My tap water is 8.5, way too high it seems for plants. Any suggestions on how to flush?
