I have noticed these little white spots on several of the fan leaves. I researched and everywhere I have looked suggests that it is the dreaded spider mite. I have spent a lot of time looking for the mites but I have not seen no sign of them under the leaves or anywhere no webs or nothing. I am stumped.

I don't have any pictures of the underside. The spots go all the way through to the bottom of the leaves. My ph has been stable. I am using a 4 gallon reservoir, 0ml(grow)-40ml(micro)-80ml(bloom)/4 gal. The TDS is around 1000ppm. I change my nutrient solution every 7 days.
This is "Blue Venom" (White Widow x Blueberry) from G13 Labs.
I will try to photograph the bottom of the leaves tomorrow. I would now but my plant is sleeping. But I'll give you one of one of some flowers in the meantime.
