  1. im running (2) 1200 watt leds with an aeropoinc system....using the general hydroponic products
    where heat is no issue i have a heater and humidifier in the room controlling the climate and im also running a co2 generator so im not using any exhaust or intake where im not having any heat or humidity issues .....i have a ph meter keeping at 6 and and tds meter close to 500ppm on my first week of veg and one of my plants is withering and turning yellow and i cant undertand why looking like it wont live,,,,some other plants are turning yellow on the tips but otherwise good.....any suggestions?

  2. They a bit frazzled dude, double check what nutes and how much you're feeding
  3. Yea 500 might be too much lower to 300 and drop ph to 5.6-5.8
  4. thanks ill try that
