Black dots on Fan Leaves?? with pics!

these black spots mainly appear on the main cola fan leaves of my purps plant(sativa). So far there's not a ton, but it has me worried. I have had to pull 6 or 7 caterpillars off since she was born. They were super small green and white caterpillars with black stripes down their backs. I have no clue if that is related tho. I use a pesticide that is approved for tomatoes and edible vegetation(this could also be the cause??). I also added vegetation nutrients to the soil about a month ago. any help much appreciated

that happened to my plant that im flowering right now but i had a bunch more and what they would do is multiply on that leaf and eventually turn all burnt. sorry to tell you that bad news but thats what mine looked like. unless this is something different.

have you tried removing it with a small stick or somthing or is it on the leaf?

Its something different, its caterpillar puke.

if thats caterpillar poop than that shit kills your leaves

how do you stop it? I have the same problem, just not as bad, yet

i dont know of any homemade techniques, try moving the spot, is it outdoor? in my situation it just stopped showing up
you cant really scrap them off cuz they are stuck on it or somthing... but when you see a big fat one just poke it with a twig and it will come off... when they spread your pretty much fucked!

Run a search on catapillar poison...I believe it's called Safer or something like that...I mike a few tablespoons with a gallon of water and mist my plants about once a month from beginning to end during grow season. I have not seen one catapillar on my plants in a few years...also spray the surronding grass and veg materials in the yard.

I would say those are eggs and that you need to spray them off with regular water, or at least try spraying whatever it is off before going w/chems,etc.

try a wet sponge?

Looks like dirt I dont think its anything you should be worrying about

im dealing with the caterpillars right now and from my experience i beleive the black pebbles to be the little fuckers shit. they eat the bud the shit it out...they suck
