Acidjjanswered grow question 4 years ago Checked the roots yesterday, no smell, run off ph was 6.2 so no issue there.
Yup, intake brings in outside air constantly at a 20% fan usage minimum have a dual controller. Exhausting via filter. 2 fans moving air inside. Humidifier you can see on the floor in the pics maintains 50-55%. Temps are around 25c. I just dont understand what it can be, same set up, same nutes, using ph perfect so no ph issue. It just suddenly came on a few days ago.
