This look like rust fungus. More ventilation, lower humidity levels, remove all infected leaves and get them out of there and burn them. Maybe do a little research. Could also just be magnesium or calcium deficiency or lock out. Cheers

What is causing this on the leaves? I'm not sure what I am doing wrong. Is it possible the heat and humidity are too high? Humidity up to 77% and can't seem to get her down sometimes. Heat is around 27/30 degrees during light hrs. Did I fuck up the transplant or grow conditions?
