I started the seedlings last night in Light Warrior. I watered with 6.5 and runoff was 5.2. The other seedlings are going in today and im thinking about watering with 7.0 to bring the runoff up a little. The bag said that the medium is ph balanced 6.3 to 6.8 so we will see which one they like the best. Thanks for the replies and any suggestions would be appreciated.
