Okay....
Just checked more than half of the plants, all leaves from old growth to new, tops and bottoms of leaves. I used a 60x-100x scope and used both 60x and 100x and seen nothing but little trichomes everywhere. No mites. So i'm pretty excited about that.
So now what? Can't check the pH because I don't have a pH pen. Have never checked the pH of any plant, soil or water in my 15 years of growing lol. Maybe its time I need one?
I dont have a pen, I use the old tried and true cheap ph meters that are sold everywhere. Probe the soil when wet in few different places. Often overlooked. Did so myslef on my last grow....was surprised to find my ph wayyyy off ! Stoked you didnt see any mites, however those in the know say that with broads ,you often wont see the mites at all, BUT you will easily spot the eggs on the undersides, long before you can spot a mite the eggs will be there. And yes they can and others have posted about this, live or stay dormant in a room with no food for over 6 months ! I have heard heat treatments work, havent done any serious experiments to test personally, but many on here attest to it. I got em sometime this past summer (I think) shut down over 2 months ago. Tossed tents and pots. Just bought a lil veg tent to get restarted, BUT not til I get some nasty chems on the shelf. If they come back I will be ready. They have done this to many others on here. These mites are the bain ! They (and more importantly the eggs) get everywhere, clothes ,drapes, walls , gear , literally everything ! The eggs can stay dormant and even overwinter for long periods of time. From my understanding, once they are in your area, your pretty fucked. Hope for the best , prepare for the worst is how im running from now on.
