Hi there. Another new auto grower here and need some help on the proper way to check the soils PH. I have a ph meter for water and nute solutions. But do not have one for the soil. I have read that some check the ph of the runoff water. Is this an accurate way to get an idea of what the soil ph is? If using a 5 gallon pot should one get a soil ph reading at different levels of the pot? Can some one please tell me whether I really need a soil ph meter or not and if so, recommend a good one.
