so this is my 4th grow (2nd hydro) and I've had some marginal success, however, i sometimes feel like i'm lost when its nutrient time. I'm using the Techniflora kit with the receipe for success. My real question is this...how should I be testing my ph....i just got a good ph tester, and i'm just not sure if i should be testing the water in the table or testing my nutrient mix or what?? I guess I'm not too proud to ask for a little help, and hopefully that will go a LONG way to making my product better. Thanks! till-u
