Hi everyone. This is my second grow. It's a super skunk auto under a 600w HPS 24/7 . Planted it January first. They're in 3 gallon pots (baby blueberry kush on the left). I'm using FFOF soul with gen hydro nutes. Haven't went easy on nutes but WHY do the leaves look like that? Curling down sharply and turning slightly yellow. Am I doing something wrong? Temp stays between 68-82 degrees.
Yellowing is usually a nitrogen def, I believe. You should google for a cannabis deficiency picture chart.
