Hopefully someone can help. I started some plants in the only soil available to me at the time which was Black Gold which had time release fertilizer incorporated in it. I am pretty confident the plants are in lockout so the other day I ph'd the runoff and it was 8.8. After flushing a 5 gallon pot for 30 minutes with approximately 20 gallons of 7.0ph tap water I was still getting 8.8 runoff. My question is since flushing is not going to help can I just start watering with a lower ph water like around 4.0ph until I get the runoff desired?
