It does appear you have multiple things going on.........the earlier pic's were mite damage, they look just like mine. The later pic's appear to be classic cal/mag deficiency (rust spots).
First thing I'd do is buy Botanicare Cal/Mag (what I use) or something similar and apply it generously (I use r.o. water and add 10 ml to every gallon).
The mite damage is harder to solve- how wide spread is it? How many plants are effected? Is the damage mainly on the sun leaves high on the plants?
