ec question...

hi guys, first post but been lurking around for over a year;

i'm growing in a 9 pot alien dwc system with a header pot (brain with float valve) and a 100 litre back up res using dutch pro nutes. grow room equipment consists of x2 675w gavitas and x2 600w budmaster led's on light movers, split aircon inverter unit, co2, air scrubber, dehumidifier and humidifier and water cooler in my closed grow space. only my 3rd grow (1st one in dwc).

here's my issue...

my water temp is 18c, ph is a constant 5.8 and ec is 1.1. plants are in 2nd week of flower. my last water change was 14 days ago and none of these readings have changed in the last 14 days. the water level in the 100 litre res has depleted by about 75 litres (which was ph'd to 5.8 - no nutes) over the week and the dehumidifier is doing its' job.

i can't understand why the ec level isn't changing. i haven't added any new nutes for 14 days. the plants look very healthy and vibrant and i'm not sure what to do or where i'm going wrong - i mean do i just leave everytinh alone till the next water change. having said that - everything is fine?
