Well it turns out those little white spots were a leading sign of spider mites. I loaned my loupe to my buddy and don't like trying to use my hand microscope directly on a plant so I did some minor surgery for inspection... and there's Nothing creepier than seeing little mites scurrying around on your babies. Pisses you off too. 😡
So we made a trip to the local hydro store and my friends there recommended Plant Therapy.

This stuff looks Way safer than some of the alternative products. In fact, it turns out Azamax from General Hydroponics (which this same local hydro store had sold me a year or so back) can no longer legally be sold so they removed the product. Exactly why Azamax is a problem he didn't say... but it is referenced heavily in a positive way in what is now my growers reference Bible which I've provided a picture of here somewhere. "Marijuana Horticulture Fundamentals" is so far beyond anything I had before it's humorous. I grew a couple 4 plant crops in my backyard about a decade ago and all I had was stuff written in the 1960s and 70s. I look back on those now and laugh - hippy sh*t.
Now the serious children have taken over, and around here it's legal now. So screw you Mr. Sessions.
