Understanding PH values

Hey there,if your runoff is lower than your input this means your medium is more acidic then your input If your runoff is higher than your input you probably have a buildup of nutrients and salts who binds with the ph down in your feeding so it gets useless so your runoff ph is higher The reading of your runoff is not your medium ph reading but is a good indication of what’s going on in your medium The only way to be sure of your medium ph is to buy a ph soil pen in my opinion I prefer my feeding ph on soil in veg 6.0 - 6.5 and flower 6.5-7 On coco I prefer 5.0-5.5 veg and flower 5.5-6.0 Hope this was of some use too u Happy growing and stay safe ✌️💪🏻🌱
