Sometimes even a complete master of a grower like myself has issues it seems pmfsl - see if anyone can suss this out!
EC rises from 1.0 - 1.9 daily
PH drops but sits at 5.8ish.
I tried flushing about a week - plants look starved so I tried upping EC to 1.6 and overnight it was upto 2.5.
Strange one - possibly root issues in nft - I will look tonight but I wondered if it was too little water flow or too large roots not getting wet enough?
Res temps fine.
