Thank you! Now I actually know why you tell me I will regret flushing.
I have noticed a foul smell in the growroom. Could root rot be the problem then? The plants are to big for me to lift them up all the way. I can only look at the base of the roots, where they come out of the netpot. The roots look nice white, and firm at the netpot. pH has increased the last 24h from 6.1 to 6.5. So that looks to be normal again for the first 24h after a waterchange.
I have been having dark leafs, burning and yellowing since the beginning. Only slightly but it has definitely increased since the last waterchange. Is it because I didn't add
calmag then? My last water only had the 3part and it was mixed in the right order. A new water change with the water in my tank (which I needed to free to fill with RO water) didn't change the rise in EC. So mixing the nutes wrong can be canceled out.
I also left some nutes in my flush water. Was planning to give it 0.2EC
