If those are mites, (picture 1 looks like downy mildew) the picture for me is too hard to determine. If it is mildew you can lower that humidity and apply some Cease + MilStop (Bacillus subtilis and Potassium bicarbonate)
If it is in fact broad mites you may as well end this grow or suffer lots of frustration. They have potassium, calcium, magnesium, iron deficiency... Sorry =(
After that, I would spray the entire grow area with pyrethrins, followed by a rented carpet shampooer and then chuck some Hot Shot Strips in for good measure.
When you start over... make sure to include using Azamax or Azatrol as an Insect Growth Regulator. It takes 7 days to become effectively systemic, but if you continue to apply any bug that eats the plant tissue or juice will immediately become unable to eat, excrete, reproduce, molt, mutate, and their hormones are tweaked way off. That way, even if you do get bugs they are screwed somewhat. I would also use some floramite. Just don't apply it closer than 46 days from harvest.
