okay I'm at day 47 from Germ on the two biggest plants. I really expected the plants to be bigger by this date. Plants seem to be visibly growing and healthy. However, they don't seem to be eating the nutrients. The TDS seems to consistently grow instead of drop. PH levels don't vary much. TDS - AVG 600 Humidity 50% Temp - 70 F Using tap water that comes out at 160 TDS. What causes TDS to rise when I'm not adding nutes or tap water? Pollutents, grime, slime? Anyone have any suggestions? I think that the plants drinking the water could elevate the levels of TDS because I hypothesize that less water would make the tds more concentrated. I have not figured out a good way to watch water levels since I cant see through RES from the outside.
