Is this spider mites? If not what is it

I cant find any other signs of infestation other than the leaves looking like this, i originally thought it was over fert but i flushed and its still gettin worse and its on all of my plants in flower room. really startin to scare me. Also sorry about shitty pics its cell phone camera...

fungus botrytis? powdery mildew? did u check the underside of the plants & did u check them with a 30x microscope or loupe?

nothing on underside of leaves.. at first it seemed like it was something like water spots or from spraying on nutes but i never did that so idk.. i havnt looked into powdery mildew but i will.

sry cant see clear enough in the pics. botrytis/mildew r indicative of high humidity, does that apply to ur situation? yes check into those 2 against ur conditions & plants.

spider mites, lol??? pretty easy to identify them, look for spider webs.... a simple magnifying glass and some looking can find them. if it looks like spots, check the back sides of the leaves for thrips. you have to look hard, they're reeeeeeally small. can't really tell much from the pics...

i've been told to turn the leaves over and blow slightly onto the leaf look for any specs moving across the leaf this would be any bugs ((spider mites and thrips)) running away from the "wind"

i would spray with neem oil then some pyrithrium or however its spelt, the bug spray for mites and all other small bugs

that would eliminate bugs being an issue if they are, also maybe cut back the nutrients a hair just to be safe?

it should be obvious if bugs are present but sometimes there can only be a few and hard to find

If there are no spiders then don't spray it with anything yet. They're not microscopic, they're just really small. You can see them with decent vision, and under a scope they look freaky! But don't spray it until you know what it is. You can kill your plants. Trust me, I lost a whole crop fighting those things.

Is there any chance it's burned? Nute or light burn?

And there are almost never just a few if your are seeing damage on top of the leaves. By the time you see the damage on top, they're everywhere.

How many weeks into flower are you?

Ok i'm pretty sure its not spider mites at this point.. I'm about four weeks into flower. i have 20/20 vision and can't see any signs of them web/eggs/movement, also my humidity is very low so i dont think its mold/mildew.. i'm upping some slightly better photos but there under hps light so.... I'm flushing again but it seems like it is either salt buildup or over fert.. i'm definitely goin to loose at least a few plants and not going to come close to my goal for yield because of it... lame..




But anyways i also have some photos of my veg plants that seam like they have a fert problem as well if anyone knows about it feel free to advise. thanks again RIU

That all looks like nute burn IMHO. I would flush for about a week, until your lower leaves start to show a little deficiency. Sounds like you have some grow medium issues.

Flush until your run off is almost the same as your water, let it dry out, the flush again. You may want to expiment with a clearing solution but I'm not sure if you want to go that far. I don't think you lose the crop, I had the same thing when I got nute burn AND light burn, and my fan leaves and sugar leaves looked like hell, but the bud was still good. No mold, no burn. Just no hash. I trimmed out the burned leaves, left what I could, and just kept trimming for the last few weeks. Probably stressed the hell out of them, but oh well. It was the only way to keep the dying leaves from stinking up my grow. Smelled like dead vegetation until I cleaned it all up, and they continued to burn afterwards even with 1/2 dose feeding. Seemed like once they burned, they were super sensitive to it again.

Good luck. Live and learn. Maybe cut your nute to 50% and work it up from there. Maybe you had hot soil and strong nutes. Whatever it is, try and identify the problem before you go nuts!

Honestly thank you it sounds like i'm having the same problem.. i'm using ocean forest soil and fox farm nutes but there pretty big plants for only 3 gallon grow bags that may have affected it.. It seems like there still growing but there is definitely a major loss of leaves. ya i'm gonna definitely do 50% fert one my next batch thats about to go into flower room.... thanks again RUI

not too keen on spider mites but heres a pic on what it does to the plants

Does not look like spider mites at all to me.
