First time grower trying to identify what these small white dots are on my fan leaves. It started on one leaf on one plant and has now spread to other leaves and one other plant in my tent. They don’t let light shine through initially however after a few days once I shine a light under the leaf I can see it passes through the spots with the white dots. Any ideas what this may be and how to fix it?
That first picture looks like spidermites. Nothing I have ever used as far as pesticides ever worked for me. I use predatory mites. Phytoseilus Persimilis. You need to know the temperatures and humididty because different beneficials like different environments. But those persimilis ate the shit out of my mites.
I agree. Flip the leaf over and use a loupe. 60x - 100x you might see the wee buggers moving around.
Post a good picture and we will I.D. what kine mite for you.
