    could be several things. I first recommend looking at it through a jewelers loupe (30X magnifyer) to see what it may be. If it is an infestation I would spray top and bottom of leaves with a spinosad product and start a systemic treatment with Azamax for 4 weeks. And remember that just a few thrips or mites should be considered an emergency and immediately treated as a major infestation. Good luck!

    You're spraying probably knocked them back. Give it a few days and check with your microscope to see if any of the little darlings are still alive. If it's spider mites, you'll need to spray every few days. Watch your new growth.

    thanks, how the heck they get on the roof. Must have strong smell, by the way the leaf with that spidermite is in the yard on a plantain plant. That is why my plant is on the roof. I did see a small web on my mj plant, but there is a huge spider on the the satelite dish near by. a garden orb spider. Maybe he shitted on my plant lol. Does my plant look healthy? I will spray again monday. When do i stop spraying? i don't know when will she start giving me bud, i guess she is flowering now.

    Pics could be better buy looks like either mealybugs (in the scale family) or lace bugs. No need to go crazy with a lot of systemics in either case. Neem oil and soaps should offer good control. Like another poster suggested it is extremely important to spray the underneath side of the leaves as this is were most foliar feeding insects make their home. It hides them from predators, strong sunlight and prevents them from being knocked off of the leaves by heavy rainfall. If you decide to treat again, turn your spray nozzle up side down to thorougly coat these little guys. Check again in a few weeks as most contact-type insectides have a short residual and some insects have larvae that take several days to emerge.

    For as many black specs as there are, that you are wondering if it could be thrip poop, you would have to have a fair number of thrips and your leaves should be showing considerable damage because of it. Something like in the picture below.





    I didn't see that in your pictures and if you are not seeing it then I would say it's not thrips.


    The possibility of it being scale was mentioned but you would normally see something like the picture below if it were scale.









    While I doubt it is the case you might have the beginnings of a case of sooty mold going on. Like I said I doubt it is the case but if it is, the problem with this type of fungi is that it attracts several types of sucking insects,like Aphids, Mealy Bugs, Thrips, and White-flies that spread the mold by walking over it and then walking around or flying to and landing on other areas of the plant(s).Eventually the mold spreads so much that it covers much or all the plant(s) and being so dark it affects the plant by inhibiting the light from reaching its leaves which stops photosynthesis, which eventually kills the plant.

    That's a long-shot though in my opinion. It is a possibility but likely one of low probability.

    just googled those lacebugs and thats how it looks, dont find any bugs under the leaves however. I think i found a spidermite under one. has a web on leaf. I found one of the leaves chewed on. there are no other vegetation up there with my plant. can i spray every day?

    bastard ate my leaf, anywho i just sprayed with neem oil and soap mixture. A whole bunch of tiny insects flew away. I saw one up close too small to take picture. I think it is a thrip, he was smaller than a ant. Blackish grey in color, so i will spray the plant daily. iwill make a garlic, onion and pepper spray and spray both of those daily. UGH
