HELP....White spots on leaves

What up guys and gals quick question my plant is flowering now outdoors, on my last visit up there i started to see white spots scattered throughout the leaves. size varies from a dime to a bit bigger than a quarter. It almost looks like bird shit but really diluted, or if someone splattered white paint on different leaves throughout the plants. I thought it might be powdery mildew, any advice will help thanx and sorry I can't get pics to narrow the diagnoses but this is all I got.

sounds like PM like you were thinking. need pics to be sure though

mildew or spidermites

spider mites a lot od tiny white spots, not dime and qauter sized white spots, that came to my mind when i read the title but then i read the description

couldnt the webbing or whatever be that size

Powdery mildew u better stop it asap, id try some greencure and check everyday to keep killing it. Dont overspray the greencure dab/sponge it with a cloth or something, goodluck.

The same thing happened to me. They could be white flies. Check to see if, when you tap the plant, small white moths fly around (they are super tiny). Those little bastards will suck juice from you plants leaving a bird shit looking spot. But this is just from my experience, so it could be anything.

I used 2 drops Ivory dish soap, with 1/8 tsp cayenne pepper, mixed into a sprayer bottle to get rid of white flies in veg and early flower, but I am not sure what to use for this late into flower? However, I know there are sticky strips made just for white flies that you may be able to find at a hardware store. I also heard that you can cover a yellow plastic keg cup with a clear cooking oil and it will attract and kill them. I have never tried this though.

Good Luck

Thanx everyone i appreciate the responses. However this last post seems more like what im dealing with. It looks like bird shit not mildew...more like its something smeared not clumped in a growth. Im in the early budding of the flowering process. I say this last post cause when i went out there i saw a few whiteish yellow bugs, relatively small in size. plus im hoping this more so than PM. I'll try and snag some photo's later on in the week. Thanx again lads

probably thrips, you can spray them with a 2 to 1 mixture of iso alcohol and water, 2 parts alc,1 part water, gonna have to spray the undersides and tops,they leave eggs, so stay on top of it, lighten your waterings. put some diatamious earth around the base.
if you have a magnifying glass, pull a leaf off the botom, flip it over and blow on it, the c02 from your breath will make them move.

The way you can distinguish from mold is that you can't wipe the white spots off. The white flies have actually sucked all the sap out of the leaf leaving no chloroplasts alive there...turning the actual leaf tissue white. Just to clarify. Pics would definitely help to make sure. If you can, get a pic of the bugs you were describing.

i see, well now that i remember when i went out there while i was pruning out these white splattered leaves i was able to wipe off the white spots hence my initial thought that birds were playing target practice on my plants. But now that i have done some more research i have came to find that this is most likely Mildew. I don't want to go the chemical route so organic is what i'll try here's what i found so far anyone try these methods yet?

Organic Sprays
Sulfur is highly effective against powdery mildew if used in a protection program with a minimum of 7 to 14 days between applications. Garlic naturally contains high levels of sulfur and a few cloves crushed in water can be used to make a homemade spray. Apply a sulfur-based fungicide at first evidence of mildew and repeat applications as necessary. Proper timing of fungicide applications is critical to successful control so make sure to begin at the first sign of the disease.


Another option is to spray once a week with a solution of baking soda. Baking soda increases the surface pH of the leaf making it unsuitable for the growth of powdery mildew spores. Be sure to spray the undersides of leaves as well as the upper surfaces when using any of these sprays.

Here's a recipe to make your own spray:
1 teaspoon baking soda
1 quart water
A few drops of liquid soap
Before treating your plants, test the spray on a few leaves to make sure they are not too sensitive.

Ok so it looks to have cleared up with the garlic cloves...i'll keep you posted but as of now this is now a proven method of getting rid of Powdery Mildew.
