Leaves half white
So I changed the water and noticed these leaves changing color. It's like half leaves though...I'm not sure if this is anything to be concerned about? Would like to catch the problem before it becomes an issue... any thought?

White powder
I've been noticing some sort of white dust on the bottom leaves and stem. I wiped them off with a kitchen towel with water 2 days ago, but i noticed today that they are back. They look like cigarette aches. I'm not sure if it's powdery mildew. I'm not sure it's visible in the pic

Powdery mildew or just... chalk?
Can someone confirm if this is powdery mildew or just chalk from misting, please? The walls of the grow tent had a little chalk on them too so that's why I am not a 100% sure. Temperatures have been quite optimal for late flower and humidity has not even been over 40%.

White residue - Mildew or Sugar?
Plants are giving off strong plant like smell rather than bud smell. Almost chlorophyll or ammonia like. Is the white residue on the leaves signs of mildew or does it look healthy and it's just sugar?

Bagnare foglie
Ciao a tutti. Ieri ho spruzzato neem oil ed è rimasta qualche goccia nelle foglie lasciando della polverina bianca. Posso spruzzare sopra le foglie solo con dell'acqua con le luci accese(ciclo h24), per cercare di tirare via questi resti o brucerò le foglie bagnando? Grazie mille

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?

On my other grows I've had some issues with pests. The worst was white powdery mold, but I've also seen leaf miners, aphids etc. I want to treat this plant pre-emptively with something like BioNeem. Is it safe to do that at this stage of bloom? Can you recommend safe alternative

White Powder on Leaf
Here's a closer shot of the white powdery stuff, only on one leaf right now. I'm going to keep an eye on it and try not to worry for now. If I suspect it's mildew, mold, or Fungus I will take action. What does it look like it could be to you all?
