So I tested my soil ph the other day, around the top half the ph is at a good 6.4-6.8 but when I push the probe deeper the soil ph then drops to the low 5's. What could be causing this? Next grow I will definitely find a better soil balanced soil. Right now it's MG organics choice. I use GH micro grow bloom.
