Nice roots, one day....gotta crawl before I can walk. The only ph supplies I have are the GH drops, works great for water or nutrient solutions but I don't think you can use the drops to test soil. I mixing soil in a solution of RO water and let it sit then test with drops, very hard to see the color w all the dirt floating in water and I don't think it was an effective way of determining ph. Thats why I did the runoff test yesterday. I realize that, like JH said in his post about the water not having time to change to the soils ph, but I figured it might give me an idea, but I just caused further overwatering.
