Nutrient Support

[425jesse]

Howdy 420 Family! Having a nutrient issue in my grow room, on one strain in particular.

-LED and CMR lamps
-Air conditioner keeping 80day/65night
-50 to 70% humidity currently
-CO2
-Mills suite of nutrients following medium schedule plus small calmag supplement
-Promix medium drain to waste

Have some intra-leaf discoloring on my sativa, but the Indica shows no signs. Any thoughts?

Thank you!
