PH testing

Sorry for insisting,i mean no offense,but i try to understand that. "In soil no need to check the runoff as soil is self buffering the PH" How can someone test PH and EC to get a better understanding of nutrient feeding or starting salts accumulation on soil? Are these tests not applicable to soil? Forgive my lack of knowledge,spending some time here and 1st grow is stressful.

Hi just a quick one I'm a amateur grower myself and I couldn't get on with a&b pk13/14 etc etc then a few weeks ago I met a old man that didn't understand why I was using them lol he then told me to use (FORMULEX) it's a universal plant food and use it all the way till flush and if you use a medium called plagron batmix you only need to add tap water for the first 6 weeks then use FORMULEX add 5ml to a litre of tap water no ph necessary look it up on google what I've told you and I guarantee you will have the easiest grow on your hands hope this helps happy smoking
