Not sure what the white dots are. Under a microscope they appear to be discolored leaf, is this nutrient burn? I did use technaflora foliage spray. I just want to make sure its not something i should be doing something about.

I think it may be. Look on bottoms of leaves for itsy bitsy moving bugs or little black dots that are the eggs.

Eggs are little white dots on underside of leaves. Spidermites start young as white dots moving and then turn red or two brown spots. The two-spotted-spidermites are Hella hard to get rid of. Leaf damage looks just like it. Look under leaf like said they are there.

The big question is what to do ?

Pyrithrum bombs like dr dooms will work fast and is organic.

If you have the two-spotted. The only way I can control them is with Azamax a neem oil concentrate. I think azatrol is the same. They are easier to use than neem oil. It can also be fred to plants as an antifeedant. Keeps them little bastard off my stuff.

spider mites
get them before they get you id say.
higher the temps and lower the humidity for a while ive found these methods to work....
theres a light recipe here
To make: Mix 1 ounce of hydrated lime, 32 ounces of water and 1 teaspoon of castille soap. Use up to twice a week.wiping the leaves clean once dryed just incase of residue etc
and a heavier one here
Pepper Spray
Target insects: All‑purpose
Just like the pepper dusts a spray made from hot peppers will release the capasaicin compound to repel insects.
NOTE: To make: Mix 1/2 cup of finely chopped or ground hot peppers with 1 pint of water. Let this sit for 24 hours. Use as is for a soil drench application or strain the mixture through cheesecloth until you have a clear liquid. Add a few drops of castille soap and use as a foliar application. Keep away from skin and eyes.
hope this helps:smokin:

I disagree with your method. Neem has been proven over the years to resolve the problem. Better yet, prevention is by far better than even Neem.

that could also be white powerdey mildew, but cant tell, either way some neem will help, but some sulfer soap will kill it imidiatly, just be carefull sulfer clogs stomata, and can caseu stunting if used to an extream, but I agree preventative with neem is the best for success. and when going flowering only neem mabey the first week or 2 before budsites start to devlop buds then stop spraying

follow his advise.....also lower your temps and humidity....that will slow them way down.

I am thinking mold the way it is concentrated on that leaf I'm looking at. Although, I could be wrong. Check the underside of the leaf as suggested already. If nothing is crawling around ... I'd do a treatment for mold if they were my plants.

Best of luck. Hope it all turns out okay for you. :thumbsup:

its deffintily powdery mildew then, keep the fans on em and the humidity down and usualy that will keep the PM away but in some areas sulfer burners are what works best

You can clearly see some small black dots in the 2nd picture,.... I guarantee those dots MOVE!!!!

It is NOT Powdery Mildew ;)



Preventing mites is the best method, but for resolving them once you have them, and you certainly seem to, Neem is my #1 Mix per the bottles instructions and spray every 3 day's to knock down the infestation, then weekly as a prevention measure.


Also, make sure your grow room is pretty much hospital clean, don't go directly into your room after working out doors, shower and change clothes to prevent a bug from hanging on you.

Any new cuttings should be quarantined for 2 weeks and watched for bugs or disease before introducing to your proper grow.

Low temps and high humidity will slow them down, but like a buddy of mine is realizing, it wont get rid of them!

Someone will eventually say, "No Pest Strip" It works initially, however mites can become immune to them, and the strips only keep them down to a minor infestation at best.


Neem Neem Neem, Weekly until 2nd week of flower,... but not after that since it'll F up the taste of the buds something fierce! But by then you shouldn't have mites anymore ;)

:S2:

I've seen several other grows IRL with mites, the mature ones will be all over the plant, but yes, immature and eggs will be found on the bottom of the leaves. Typically near the veins where they can hide.

I think i caught them early because there doesnt seem to be any more spider mites, yay.

but now i seem to have the "tacoing effect" on some leaves and many new leaves are curling down like talons. and one leave has a couple brown spots. Let me provide you guys with more info so you can help me out

Im growing under 400 watt and 4 100 watt cfls for side lighting in an aeroponic system with hydroton rocks. My humidity is low at around 25% and my temps are between 75 and 80 degrees. I am using the techniflora starter kit and recently started using neem for spider mites. My reservoir is at just under 400 ppm.

I have read that the curling could be from too much Nitrogen or possibly a magnesium deficiency. What do you guys think?

Here are some photos to help you guys out.

Yeah, that's not from the bugs. Not seeing any bugs now, good job!

Looks PH or nute problems, I"m not a hydro grower so I can't help much.

its always worked with me my father told me the recipe and tried and tested,BUT i agree neem oil is much better:thumbsup:

Someone already stated that you should not use neem past the second week in flower.

THere is a tobacco leaf extract that kills on spot and can be used up to the day of harvest. Liquid Ladybug works well too but is expensive, they are organic and safe to use up until harvest.

1st dont post your pictures on photobucket and second dont use clones from anygrower, good way of avoiding spidermyths. And if you get them close to harvest. Harvest it, hang your buds on a string and placed fly catcher tape (that they sell at the dollar store) a both ends of the strings and watch the spidermyths leave your buds and get stuck to the tape. and if you get them during the grow shoot the under side of the leaves with whatever solution you want. Water and a little non toxic dish soap can work. the principal is that it's oily and slippery for the spider and place flytape on the soil/grow medium and around the pot any remaining spider will go and get stuck to the flytape. And be sure to desinfect the grow room and surrounding areas. take a two week break between your infected grow and the newone spiders die and leave if there is nothing to feed on!

just hanging them will make those little buggers crawl up and off. ive heard those strips will off-gas and penetrate your flowers. i wouldnt chance anything with my flowers, if its lost it is lost. remember where that stuff ends up. after veg is the last time you should apply anything. thats just me, though.

maybe I dont know I dont get spidermyth in my grows . If the flytape does not come in contact with the buds I dont see how contaminants would transfer to them. But good point!!
