Having a problem the leaves seem to be rusting out. I had a spider problem in week 5 and this plant was affected the most by the pesticide i used.

Make sure you only apply the pesticides during lights off.. if you were growing hydroponics, I'd suggest pressurized cold water spray for the mites, they fall off in the cold, and the pressure knocks the eggs off.. very in safe pesticide water is.. rusty leaves may be burn damage but it might be a pH issue as well as a calmag issue, need better pics to tell. Cheers

Your plants are showing a shortcoming.
I would flush them 2 timess with normal water. And then start giving some nutes again.
Or i would give some calmag just to be sure.
Happy growing

I think my plants are suffering a Phosphorus deficiency due to lockout due to low ph of soil. My first flush only helped for a while. As soon as the medium gets too dry damage resumes. I went to check on them yesterday and the amount of damage they took in 24 hours was pretty bad

Should I harvest early? Light stress, leaves browned and dried out, buds are all amber pistilsSo this plant has been suffering from light stress for the past two weeks or so. I have removed all the dry and brown leaves. The buds still seem fine-ish. Should I just give her the chop early and save what I can? She's been flowering for some 6 weeks.

Deficiency/Light Stress IssuesWhat else can I do? Brown curled tips and spots on older fan leaves climbing up towards main cola. Flushed with pH’d RO yesterday, but was only able to get pH to 6.7, also added small dose CalMag at end of flush. Light wattage has also been reduced by half for the last week.

Browning of leaves, heat burn or pests?Plants are showing signs of browning, and other weirds leaf markings, kind of grey-ish not too pronounced. It's been very hot and sunny here for 5 days, temps reaching above 37°. I left them in the sun during this period, is it heat stress? Otherwise growing nicely.
