Hello all, I have a northern lights auto from seedsman in about its 4th week of life. Ever since about week 2 it has developed these yellowish spots on some of it's leaves. They dont appear to spread very quickly and dont appear to be holding the plant back, but I noticed what looked to be the start of this on one of my zkittlez autos so I figured I'd try to figure out exactly what was going on. I PH my water, and the plants have been receiving low doses of nutrients, besides calmag which they get at full dose due to growing in coco coir.

Coco coir in fabric pots
2 vander 2000w full spectrum LEDs
GH Micro, and grow and calmag
PH around 6.0
Fan and humidifier running
Temps around 77 degrees
