It's not a nute issue... I think you may have a bug of some kind but I'm not sure. Have you looked underneath the leaves?

Spider mites?
My partner just cut some clones off of a pre-flowering plant & put them in a root rain spray cloned. Been 2 days since he cut the clones. No roots yet but he’s wondering if he has spider mites & if so what he should do. Do you all notice anything wrong?

I'm starting to see some white spots on one of my plants and the bottom leaves are stating to yellow is it just fungus or potentially thrips? My other plant beside it doesn't seem to have to have the same white spots on it so I'm not sure if its spreadable.

Is this powdery mildew?
Is this powdery mildew? I am seeing some white spots starting to form on the underside and top side of lower fan leaves. Would adding an oscillating fan help prevent anymore white spots from appearing in the future or will I need to apply neem oil or something?

how many times should we spray with milky water in case of powdery mildew when we are in bloom? do you have to spray with this solution every day?
Several people here advised me to dilute the milk spray with water, I did it, I diluted 400 ml of milk with 1200 ml of water, then I sprayed the plants in the tent, since they are grown in scrog, it is difficult to get everywhere.

Possible mold/mildew - I ask a ton of grow questions but figure someone else might learn if I do well or f up. Good community here
Mildew? This has been on certain leaves of my plants since I got them so I didn't think much of them. But as I'm about two weeks into flowering, I want to see if this is possibly an issue. Have okay airflow in the tent but could be better. Humidity is 55% atmosphere. Thoughts?

Small white spots on leaves in germination phase.
Does anybody know if those small white spots are ok? I have water 7 pH and I add some citric acid to lower it to 6 pH, when I sprinkle the soil I lightly sprinkle the leaves as well and I'm not sure if it's the effect of dry citric acid or something else. Thanks.

Difficulty identifying leaf problem - maybe it's insects?
I'm having trouble figuring out what's going on with my plant. The cotyledons and lower fan leaves are getting irregular shiny patches varying in size underneath, with yellow spots directly above them on the top side. It's really hard to photograph the shiny patches. Thrips?
