Hey guys just wondering if this is what I think it is...powdery mildew or is it nothing. If it is mildew what the hell do I do. From what I see it’s only my one plant affected. Should I cut the bottom leaves off that are affected. Plants are not getting any nuts yet so I don’t know what else it could be.

many opinions greatly appreciated.

last picture is of the second plant that doesn’t not look affected

also what ever is on the plant cannot be wiped off so it leaves me to believe it’s not powdery mildew?

Any chance it could be thrips? I don’t see any bugs on the leaves but also this is to the naked eye. Maybe I should invest in a magnifier?

Not PM. Looks more like mites, but very early on.

And mites are very hard to see... So Ya. magnifier unless you got super powers.

You can see thrips. Mites are tiny. 100x-150x mag and you can see them.

Lookslike Spider Mites. Those reddish spots will turn yellow and if there are enough of them, it will kill the leaf. A bad infestation will have webs and trash your grow. Spinosad (Dr Dead Bug) works well for them, but they are very hard to see. Look at the undersides of the leaves.

Looking at the undersides I don’t see anything moving. I’m guessing if I invest in a magnifying glass I may see something.
