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?
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.
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?
