2x Northern Lights Auto DWC - 4 gallons

Week 4 - Vegetation stage is well underway, both plants are growing fast and are developing healthy roots. Today, I measured PPM, EC, PH & Temperature of both DWC tanks Results: PH: 6.1 EC: 2800 PPM: 1300 - Added 2 litters of fresh water into both tanks to dilute PPM/EC. 1300 is quit high for early vegetation stage. - Tested the solution again Results: PH: 5.9 PPM: 750 EC: 1900 - Added 5ml to each tanks of Advanced Nutrients Sensi-CalMag - Adjusted the PH to 5.7 I suspect I have been over feeding in early veg stage, 1300 ppm was quite high for weeks 2-3. I think it may be caused by the plant consuming more water than nutrients, and since I didn't made any adjustments for two weeks the solution got more concentrated. Will monitor PPM closely now :-) Cheers!
