Happy Friday my friends and happy Halloween! I pray you are all safe and have a wonderful weekend!! I wanted to ask a question. Is there a video or resource/video here that's for dummies on how to switch from the two part (A and B Tower Garden products) nutrients to the 3 part @Chad Miner recommends? I'm watching the videos, bought a EC/PH AC Infiity tester and that's as far as I got. I don't know how to pivot to A use the meter, and B how to switch to the General Hydronics nutrients. Thanks for the help in advance my friends!!
