Looks like you have bugs in yer garden. Either that or its some type of fungus.
to see russet mites you need 100x they are tinyI've been checking thoroughly everyday even under microscope.. havent seen any on the leaves or under them.. no eggs, no flying thingies nothing.. any advice on how I can spot them?
This is not russet damage. Having battled russets myself recently, you can just barely see a russet mite infestation with the naked eye...it will look like very tiny brownish fibers that congregate where the leaf meets the petiole and usually start from the bottom of the plant working its way to the top. As infestation progresses, the new growth will grow out with the leaf edges severely curling upwards.to see russet mites you need 100x they are tiny
don't wait until the damage is that bad with a 100x you can see eggs and stop the little fuckers before they do any damage. I have a 60x that doesn't show single mites or eggs so I got a 100x and it does.This is not russet damage.

About 40x is enough to positively id russets.
This damage looks typical of either thrips or spider mites. Thrips are easily controlled with spinosad, but I hesitate to jump straight to spinosad because it is harmful to bee's.
