I have 2 autos going and use ph perfect advanced trio, fish shit, and cal mag. I just got a TDS meter and notice if I put the amount for autos that my tds is only around mid 400. How do I add more safely to get around the 1000 ish range for flower without nutrient burn. Got a lil already from over feeding now I’m a little gun shy. My tap water is only around 50 TDS just for the info. Any info please and. Thanks I’m andvance
