so if you guys look at the leafs on the jack herer, there are white spots on it, and if u look at headband, there are benches of small ass black, yellowish shit on my leafs, i believe those are spider mites?
you have mites for sure, but that brown blob of whatever it is, doesn't have anything to do with the mites. I can't really tell from the pic what it is. It looks like a big worm poo.
If your refering to the (scales) on your leaves, its mites, gotta hate those little basterds.
I use house plant spray, and i usally takes care of them the first shot.
Or you can try ..dont bug me.. it that stuff works really good
