Mites! Try some Dr Bronner's Soap- cheap, safe and it works! Just be sure to spray the underside of the leaves where the mites hide. With small plants, I make up a bucketful and just dip the whole plant! The peppermint soap is my favorite. How to Use Dr. Bronners As Insecticidal Soap.

Potassium Bicarbonate or Sodium Bicarbonate. = Baking Soda. 1 tablespoon per gallon of water. Apply weekly. BNW
Neem can leave a rather horrible taste in your buds if used too close to harvest. A little bottle of Dr Bronner's was about $5 last I checked. (I can get a big bottle of it for $12 at the Grocery Outlet) Nice thing about using insecticidal soaps, is that you can rinse the soap (and the dead bugs) off with plain water. No residue on your buds! Granny
Do you spray this on the leaves and is it best to do this just before th lights go off if you are growing indoors?....Thanks for your help

Yes it is just sprayed on. All the Bicarbonate does is raise the PH of the water high enough to break up the mildew. It's not a cure but more a treatment and as non toxic as it gets. A teaspoon in a pint / quart spray bottle is likely all you need for an indoor grow. I treat outside and yes morning or evening is best but I've sprayed mid day sun with no trouble. BNW
Yes, you spray down the whole plant just before "lights out", being sure to get the underside of the leaves! You want every bit of the plant dripping wet. Then put a fan on your plants to help them dry. And peppermint Dr Bronners smells far better than neem! Don't worry about the soapy water getting in your soil. At the level it is in insecticidal soaps, soil bacteria will take the soap and change it into simpler compounds your plant can use. So follow the recipe and you won't have problems. You need each and every mite to get wet. The soap in the water cuts through the waxy coat small insects have to keep liquid from evaporating too fast from their bodies. The mites die a horrible death from dehydration! I expect that the peppermint oil isn't pleasant either. (I'm a sweet old lady, but I HATE mites!) It's best to repeat the treatment after 3 days, just in case an few eggs didn't get wet. I usually don't bother to rinse the plants down with plain water until after the second treatment. I know that's more trouble than the "one and done" poisons, but do you really want to smoke poison? I sure don't! Granny
