Hi Greg, in this case, I think you're going to need a pH meter rather than a liquid drop test, as you rightly point out it's going to be hard to gauge the pH by colour when the nutrient solution is so dark. The Milwaukee pH tester we offer is very reliable, effective and affordable too! Hope that helps, all the best and happy growing!
