theys using alot of water at the mo, over the last two days i've had to top up about 6lts,each day thing is my ec is shooting up from 1.8 to 2.2, this happened twice, i drained and refill my res last as a weekly ritual and set ec to 1.2-1.4 tonight its 1.8. any ideas y the ec is going up so much? does it mean the plants aren't taking the nutes, or is it simply just evapoarating away, i've got a dehumidifier in there keepinhg the humidity around 50% as before it was hitting 80%
has this happens to anyone else?
