guys, just received a TDS pen. Reading on the ideal levels to measure posed a question:
growing my auto in hot medium (19-04-04) but now 35 days on and with two profound flushes, all of my research for noot strength (in terms of percentages) have all been around 25% graduating to 50% because of their strength.
abiding by a 25% dilution and now heading to pre flower using a 50% approach, i measure only 520 ppm with my ph’d tap water around 5.8, this at half strength measure is still under the ideal in the chart. should i consider increasing the noots to 65 or over percent to obtain the ideal ppm read? or obey the legacy knowledge of some noots being overly strong (especially in fertigated medium)?
Plants look like this: (1 liter every four days)
