Hello I finally bought a ppm meter and was wondering what level should I be at? I have about a half gallon on distilled water per plant with a bubbleponic hydro system. I use fox farm trio nutes and only use 1 tsp per plant per week. My one plant was reading 230 the other was at like 90 without nutes. I am on first week of flower. I am a first time grower so this is my trial and error run. Any advice will be nice. Thank you!
