White dots on leafs? But no mildew

Listen to me .. use organic insecticide from Walmart and buy lime AND flush. You gotta check this PPM if high or not.

You have spidermites. You can see them on the leaf. the tiny black/red dots. If you are in flower, peace be with you. haha Predatory mites are your only option and may be too late.

Then you have a pest issue. A lot of pest are super small. 1/20th of a inch. So unless your are looking under 100x magnification you may miss them. Russet mites can barely be seem under 100x magnified. If not flowering you can use neem oil mix. I spray on heavily and all over good. I let it sit about 30 mins. Then I rinse plant off. I wait 3 to 4 days and repeat the process. By this time it will kill or chemically sterilize all the bugs. Do not spray it on flowering plants. Neem taste gross. Plus with what it does to bugs, I prefer not to have it in my system. If in flowering. Best you can do is go rinse pest off plant with a good fresh water bath all over. Wash everything off good. It will remove a lot of bugs.

looks like mites or thrips. chek undersides of leaves for mites small dots, and in the veins for thrips, they are yellow to brown/black and like 1/3 a rice grain.

They are verry small by the way, hiding in the leave ribs on the leaves, not under.

I think it's Thripse and it's lots. You can try neem oil but I doubt it will get rid of them all. If there are no buds take Spruzit, if there are buds wipe the leaves with kaiser Natron water. Much success 🤞and Happy Growing
