    Default Are these Spider Mites?

    First grow is off to a great start, however my leaves on 2 plants have developed some small yellow dots on the lower leaves. At first I thought it was calcium deficiency as Im using coco and didn’t prep it first with calmag, but after a couple more days and some more research I’m not so sure.

    Is this / are these spider mites? Having never identified them before it’s a bit tricky

    No worries mate was only kidding. Hmm that looks pretty suspect. I have nigh on zero experience with bugs but I'm sure someone will spot this and help you out

    Can't really tell from the underside of that leaf that you took a picture of, but down on the bottom where you see all those spots really looks like spider mites.

    If you are not in flower and in the United States you can just pick up some fruit tree spray. It would be, if you look for it, sulfonated neem oil and pyrethrin. You would have to spray every 3 days for a couple weeks and clean your growing environment.

    Those appear to be spider mite eggs in the zoomed picture. Damage to leaf appears to be some sort of mite, in between margins, though when i had them the damage appeared to be white. Might also be thrips. Thrip damage will have straighter-more defined edges.

    Jingo is absolutely correct, you need some type of flower safe chemical. If youre not in flower now, you will be before they are eradicated. Dont waste your time with predator bugs. Theyre a good resource in controlling healthy pest populations, not eradicating well established infestations. At this point they are having adverse effects on your plants, its apparent from the leaf curl.

    I have used dr zymes and it works great. Safe for flower. Pricier tho. Probably the same active ingredients as what Jingo suggested, only what he recommended would be considerably cheaper.

    Dont be afraid to post pics of the whole plant. Overall plant health is important when determining treatment method. Might even get you a wooden spoon, which is the best bling on the site imo

    Really you need to look on the under side of the leaf to be 100% sure, as it could be calcium deficiency or something else.
    you can see them move and there lots of small black dots

    Hi guys,

    Sorry for the slow reply. It definitely was the dreaded mites. It took about 3 days to get rid of them using 1% h2o2 as a foliage spray twice a day, and I carried on for another 3 days to make sure they were gone.

    The results from using that (I had it handy so no time waiting for a delivery letting the bast@rds multiply) were great. I did suffer some mild drying of the leaves, similar to a mild wind burn.

    Here are the gals now:Click image for larger version.
