Sounds like "the borg" (spider mites), to me.

Buy a fresh "no-pest strip" and hang it on a lower branch.
Then get a large trash can and upend it over the plant at sundown.
That holds the vapor in. Kills adults and larvae.
Remove the can and strip at first light.
Repeat 2 more times in 3 to 5 days.

You might also want to mulch heavily under the plants to annoy future soil dwelling pests.

Also works for thrips and aphids.
Ride on!

Weezard Reviewed by Weezard on . Problem with outdoor plants! Hi, My problem relates to white spots on the leaves, with black spots on the underside of the leaves. I kinda think this may be spider mites, but I'm not totally sure. Upon closer examination, I noticed tiny bugs on the leaves that were brown and grey in color. This is my first grow, so I am not sure what to do. They have been flowering for about a month now, and I was thinking about using some neem oil. Any help would be greatly appreciated.
