Yes. I have well water also, so that helps. Have a reverse osmosis hooked up, but found my plants look healthier with well water out the faucet, so use that mostly.Yeah, I've checked my water a few times since I've been growing. It's always been dead on 6.0
Good ol' TX well water. High mineral content too. Cal/Mag deficiency is few and far between with these girls.
But, I was never really sure. Now I know.
