If it turns out not to be spider mites, it might just be thrips.. Here's some pics of thrip leaf damage..

What do I use to get rid of them?Looks like spider mite damage. Look for little webs on the lower branch/leaf junctions to verify. Examine underside of leaves for evidence as well. Sometimes you can see them moving up/down the stalk.
hank you so much you are Absolutely awesome.Here's one method I use that works very well for spider mites.
First, make a solution of rubbing alcohol and water, 9 parts water to 1 part rubbing alcohol (I use 70% isopropyl) put that in your sprayer and spray the entire plants, making sure to get under the leaves as well as the tops.
Let it dry. That will kill all the adult spider mites instantly, won't harm your plants. Just make sure you don't go stronger than 9:1.
Second, make a very powerful neem oil solution. I usually double whatever it says on the bottle. So if it says, let's say, 2 tablespoons per gallon of water - I'll use 4. Make sure the water is warm, not hot, but warm, and constantly shake your sprayer as you spray your plants. Again, cover the entire plant, under and over the leaves.
Let it dry.
Third, take some diatomaceous earth, by the handful, and fling it at your plants, dusting the leaves. Give them all a good dusting, and sprinkle some around the top of the soil. Spider mites will lay eggs in soil, too. This gives any hatching eggs no chance to mature, they'll eat the DE and die.
2 days later, repeat the process, until they're gone.
You can also use Lemon oil in the same way as neem oil. This is actually preferred over neem oil, especially during bloom.
I hope this helps, good luck!
It's not spider mites. It's a powdery mildew that is caused from moisture and maybe the plants being close to each other. Get a spray bottle, fill it 40% milk and the rest water. On a sunny day spray the leaves. What happens is the sun turns it into a protein and kills the mold .Do it every 7 to 10 days.My friend has a nice little plant growing and i looked at it today and there where all these tiny white spots on it, im attaching a pic any help would be great thanks
