Say I wanna go soilless(Vermiculite, Perlite, Peat Moss). I know I can use my Hydroponics Nutrients(which is Dutch Master Gold) But!!!!! Do I still check the nutrient solution PPM with my TDS meter before I feed OR am I gonna have to get a meter to test the PPM in the soil(if there is such a thing)? Now I know the pH then is a little higher ranging from 5.8-6.5, but do I test the pH with my solution pH tester before I feed it to the plant? Thanks.
