city water in my area is 7.5 to 8 and 550ppm if meter is to be believed, with chloramine l believe it, use every watering and no lockout if ph meter is working proper. Vinegar, lemon juice or ph down was all l used. And no buildup! Dont water to runoff either. If ph meter was spot on l would have no issues at all. Drops removed all doubt meter was reading 3 points too high. So l was feeding acidic with almost no side effects. Until it was too long in zone. 2.4 and 3.4 were my 5.4 and 6.4. Big differance now. Using soiless medium with mycorhyzae. Promix hp m.
