Hey RIU, I just got my digital ph pen. I calibrated to 7.0 with the solution it came with. I wanted to test my soil ph. So I just watered and used some runnoff water to test. Im using distilled water with a ph of 7.2. The ph of the runnoff is 6.7. My question is did I do this right? Is 6.7 a good ph? Im using fox farm ocean forest soil. Also my pen said not to let the probe dry out so Im keeping it in the solution that it came with. I put some solution in the cap and put the cap on the pen. Is that ok to do? Thanks!
