Letterhead954 Posted July 30, 2012 Report Share Posted July 30, 2012 I've been using Roots Original for veging. A while back I tested some runoff and found that it was really acidic. I use a pool tester ph kit, and the runoff was red. I thoroughly flushed two plants, and it seemed to help a bit. I've noticed that all my small plants, in 6" pots aren't looking to good and are growing very slowly. I flushed one tonight with high ph water (around 9), and it still came out acidic. Have I just gotten a bad bag of soil? If I keep using this bag, how can I get the ph down? By the way, I always ph my water to about 6, Quote Link to comment Share on other sites More sharing options...
