Should I be worried about the dark shadows on these leaves?. It's OG KUSH in coco just flipped 5 days ago
Under leds. There is also something going on with the edge of the leaf pointing up.
Thank you as usual for the
Less darkness and more lightness. this is normally caused by lacking Mg,

Leafchart thats usefull. save it on your desktop or mobile and reference it.
like bros said its the sign of lack of Mg (magnesium) that i think occured because of Wrong P.H or over feeding.
check your P.h levels to be between 6 - 7 and also lower dosage of your feedings.
