Three weeks into flower. Orange spots forming on leaves and spreading. I’ve been feeding cal/mag with every weekly feeding so i’ve Been ruling out calcium. My room gets pretty cool at night with humidity rising around 70%. This is leading me to think rust fungus. I have never flushed and last feed was 850ppm.
