  1. my friend has 3 plants in a 4 gallon tote (dont ask) with airstone and pump.
    Its surpisingly doing great, now its ready to bud but water has to be added every 4-6 days.
    Should nutes be added to maintain concentration or should fresh water be added?

  2. nutrients to maintain or adjust tds, use an addback formula
  3. I don't have a ppm meter
  4. well theres your first problem.
    You will more then likely have to add more nuts. though go buy a ppm meter, even a cheap nasty one will do.
  5. well its not my grow if it was it wouldn't be in a 4 gallon tote lol... but anyway my friend wont do that how bad is it to lower the concentration of tds?
    Will it be ok if fresh water is added until 2 weeks when the water is changed?
