Hey everyone, 2 of my sour jack sativas from Cks are starting to yellow. I'm pretty sure it was a heat and humidity problem, I was at temps above 30 degrees Celsius and at a humidity of 60%. Now I've got the temp down between 25-28 degrees Celsius with a humidity between 45-55%. There are growing super slow but don't seem to be yellowing as quick. Could this be a ph problem because I have not been checking my ph when I water? Any info is appreciated!
