    Default Spider mites



    Hi all I'm thinking I may have spider mites after researching these splotches.
    I'm not 100%, maybe just light burn from water droplets or something maybe from humidifier??
    I can't seem to find anything under the leaves with the microscope, I was trying to zoom in on the little specs I seen under there but unsure whether it was just soil or bugs maybe?
    I've just sprayed Epsom salts in there and have them a really good drenching to hopefully run anything of the leaves.( not because of this, but just for magnesium nearly 3 weeks in)
    I will spray this plant invigorator in a few days to try and rid any pests that are there, if any.
    Thanks for looking??

    Doesn't look like spider mites to me but the only way to tell is to get a good close-up under the leaf. You can see them really easy with Jeweler's loupe. They also tend to like to climb up to the top of the plant every night after lights-out so you might look around at the top of your plants for the problem.

    I agree ^^. You need to check I've leaves out so be obvious if it's bugs.

    Hope it's not, so in your opinion what do you think is the best defence presuming it was?

    Pick a leaf off the plant, use a loupe to inspect the underside of the affected leaf.

    These are eggs of the 2 spotted spidermite, look very closely, if you have them you will need to jump into action. I would suggest this to start:

    The first will do a good job at killing the adult mites, the second will kill the eggs & remaining adults. You'll need to treat the plants for up to 2 weeks. The above will be fine during veg but not flowering. If vegging, spray the entire plant, under leaves, stems, pots & general area. I have a thread regarding how to deal with spidermites, it tells of a pepper spray that is 100% organic & that can be used in flower.

    Never actually thought of taking a leaf off to inspect it, so simple yet so awesome thanks, I'll find the thread up!

    Loki I've seen them little eggs just now. Little beggars aren't invited and they're getting turfed out, I've given them a good dose of the stuff I've already got but will also get this other stuff you suggested as its not worth risking. Thanks for your help, legend, you've saved me my smokes!

    I had spider mites recently also. I was devastated thinking is never be able to totally get rid of them but I drenched my plants with neem oil every 3 days for about 2 weeks and it completely irradiated them. The neem oil is without doubt my favourite growing product and i have and will use it as a preventative from now on during veg and early flower

    Do the biological predators of the spider mites not sort them?
