guys the best and safest way to kill spider mites is to always plan ahead and anticipate them...flowering buds are a magnet for these little critters...once infested its hard to completely get rid of them without causing major stress to the plant.

so what to do?

Buy "Fungicide 3 in1" by Garden Safe ($12/bottle at Home Depot)...this is a great organic product that not only prevents all forms of infestation but also prevents mold and allows you to foliar spray the plants right up thru week #8 of harvest...yep you hear me right...if you were rountinely spraying your babies with this stuff you can foliar spray them with water mixed with a light organic fertilzer solution...its 80% organic NEEMS oil

how to apply?

mix one teaspoon of Fungicide 3 in 1 with water in a typical 32 ounze foliar spray bottle and also for added measure you can add a small amount of your favorite "organic" fertilizer..I like Fox Farms products, and always add it to my foliar solution...about "half" a capfull of Fox Farm Tiger Bloom to the NEEMS oil foliar solution.

this way you accomplish three (3) things:

1. fungicide--mold can NOT grow easily in this enviroment
2. Spider Mites and other critters avoid your plant and can NOT
lay their eggs in your planst soil or on the undersides of those
larger fan leaves near the bottom of the plant.
3. foliar fertilizing directly to the growing buds...always good if temps are warm at night (I will explain below).

but its best NOT to spray your plants with the lights on..the NEEMs oil can cause leaf burn to the petiole (leaf stem)..so its safest to apply it after the lights go out or about a half hour before they are first turned on..this allows the NEEMs oil to dry completely on the leaves and act as a guard against mold and critters...and it does NOT effect the taste of your buds...its clean.

so, do this about twice/week during the Vegetative stage and once/week during the Flowering stage and keep your foliar spray bottle filled with this combination: fungicide/fertilizer solution.

also for those outdoor growers, its best to NOT foliar spray after week #4 of the Flowering stage (that's when the buds start to get fat), if the temperatures at night dip below 60 degrees...when it gets cold at night, that's when MOLD can form on petiole (leaf stem)and cause bad taste..so warm temperatures are what you want when you foliar spray flowering buds outdoors. You want them to dry out after being sprayed.

with indoor growers this is not as big a problem since temperature is better controlled when it gets dark in a grow closet.

also foliar spray the underside of those fat fan leaves..that's where the spider mites lay eggs to shield them etc...

thus you can be biug and mold free right thru week #8 of flowering stage or evn longer if your lighting is poor..less lights means smaller buds and more time beyond week #8 to completely finish.

p.s.
do NOT use any fertilizers in your foliar solution that contains Nitrogen after about week #7...you want your buds to taste better...just use somethings with Phosphourosus/Phosates only at that time in the flowering stage.
