I dealt with spider mites not too long ago.

Buy Diatomaceous Earth and sprinkle it around the base of your plant. Buy Neem Oil, insecticidal soap, and an insecticide like Captain Jack's Dead Bug Brew that uses Spinosad. Every 3 days, spray the tops AND bottoms of every leaf with one of these, using a different spray each time. Continue this for 5 weeks after you don't see anymore mites.

I might be an idiot for this, but I sprinkled some DE into a fan and blasted it all over my tent. Stupid or not, I didn't see a single mite for the rest of the grow after that combined with releasing predatory mites.

This might cost you 50 bucks or so, but it's worth it to knock them out now and not risk them returning or wiping out your plants.

If you wanna get a better look at the mites, you can buy a macro lens for your phone here. You could also buy a jeweler's loupe here.

20x?!! Are you sure she's using a true 20x loupe? If you picked up a cheap loupe online, chances are, it's not a 20x. For instance: http://www.amazon.com/SE-Loupe-LED-Illuminated-21mm/dp/B0013E3DAG => advertised to be 20x, but turns out to be ~5.5x.

I would recommend first figuring out the minimum magnification power your wife needs to read small text. Reason: There is an inverse relationship between magnification power, and depth of field and field of view. Meaning, there is no 20x magnifier that can give you a huge field of view (I have a true 20x, and dear god, it is useless to me since it can only view about 1 character at a time).

Here's an example of the tradeoff: I own several Donegan OptiVISOR headband magnifiers. At first, I ordered their most powerful model, the 3.5x. The 3.5x has a focal length of 4", and a depth of field of about 1". This means, in order for me to have a clear image of what I'm observing, I need to make sure I maintain a 3" to 5" distance between the lens and the item under observation; it was just exhausting.

After trial and error, I ended up with the the 1.75x. It has a focal length of 14", and a depth of field of about 4". Which means, I can keep the item under observation at a distance of 10" - 18", which is much more forgiving.
