How do you use a TDS Meter in regards to fertilizer solutions for non-hydroponics? I bought a $20 Hanna TDS & the directions are more specs than instructions; what should I look for, readings, etc. I want to water/fertilize seedlings in soil-less mix which obviously lacks
nutrients with 3-2-2 liquid fish solution & maxicrop 1-0-4 seaweed mix. Seed;ings aren't big enough for transplanting [outdoors] yet, most 2-3" tall. Mostly veggies like tomato & peppers & cauli. Thanks.
