i see some really clear signs of a cal/mag deficiency, they look overwatered and overfed - maybe your PH is off too, a little heat stressed maybe, light green yellowish new growth is normal most of the time. You should try to provide as much information about the grow as you can before asking for help, plant problems arent always obvious till we know what the environment is like. temp, humidity, soil, water, PH, PPM of nutes, what nutes, light cycle? what light, size of the pots, strain, thats just to name a FEW my guy.

still gotta be just as hard to water all of those. You could come up with a pretty simple design for a future grows. Looks like the majority are pretty healthy.

Spider mites tend to lay their eggs on the undersides of the leaves and scattered all over the place rather than in clumps so that may be some sort of fungal growth like powdery mildew. For shit like that I use dilute potassium silicate as a foliar spray. Kills the crap out of PM with one application in most cases. I'm pretty sure it's effective against the eggs as well so worth a shot. Good for your plants in any case.
Looking over that room pic of the plants they don't all look very happy to me. What are you using for water? I only use RO or distilled water with a little CalMag to keep my girls happy tho I don't run a room full like that. If I were I'd for sure be using an RO unit to get my water but am still buying 5 jugs/week for drinking water and for my plants. Got my eye on a nice little 4-stage unit with built in UV sterilization for only $295 and will likely order it in the next day or two.
I mainly grow in DWC or soilless with hydro nutes. The last couple of years I've been experimenting with adding organics like EWC and composted sterile manures to the mix but that has never gone well so sticking to ProMix HP with hydro nutes for my potted plants. That always seems to work well.
Good luck!

I was doing my research and I think I know for sure it's not powdery mildew I think it's the community like a kid trying to grow something you don't mean this like like at Acme so I'm thinking is my community was high cuz last night my my humidity go up to 72 cuz it's been so hot here in California so and I know it's not spider mites or any eggs cuz I try scratching and it's a very like a very hard it doesn't come off I rip the leaf off just to make sure there's nothing that's the only leave that I see around other plants and another thing is yeah they looks sad but I just fed them so they should be lifting up again and and the yellowing is kind of its kind of because of my lights it's given that kind of a bright neon green kind of look but the only question I have is I'm having problems with my temperature everytime I close my door my bedroom door my temperature just skyrockets any ideas what how how can I fix that I mean I have a evaporator cooler and a dehumidifier and a intake fan Anna Annabelle couple fans in there any ideas

What have you got going on for an exhaust fan? With that many plants you should be running at least an 8" inline but if your intake air is already hot like it is in your location that won't cool much but will reduce humidity if the intake air is lower than the room air. You have to remember that all those plants are adding lots of moisture to the air too and keep doing that for while after the lights go off so if you cut off circulation then the RH will spike. This is normal for grow rooms that go cooler with the lights off even tho there is not a lot more moisture in the air but at a lower temp the humidity is relatively higher thus the name Relative Humidity or RH. The same amount of water in the air at 80F will show a lot higher RH at 70F and even higher at lower temps.
Good thing you took that leaf off. I found a little oval shaped patch like that on one of the leaves on my outdoor plant and put it in a little jar to see if something hatched out of it. It just dried up so I tossed it out. Maybe it needed to be attached to the leaf to do anything but now I'll never know! lol
High temps and humidity are not a big problem while you are still in veg. with any luck things will have cooled down by the time you get into flowering. Those conditions aren't even a big problem until you start getting colas forming around the middle of flowering when you want lower RH to help prevent bud rot. Lots of air circulation helps prevent that too.

Ah so I'm good. But yes my wife told me that 1 plants from middle to bottom there is 5 leads with white shit on it... how can I fix fast?
Second the thing is I want to close bedroom door cuz its loud n bright, but if I do my temps go high like 85-88 but RH goes to 65-75%
How can I keep door closee n keep it cool?
Does reflecting sytrafoam panels 1in keep heat out?
The thing also this dam house has no isolation, OR atleast not good at all,
I have a 8 in ac infinity inline fan

White shit on leaves is usually powdery mildew. Best treatment is better airflow and lower RH but using a dilute mix of potassium silicate to spray works very well and is a boon to your plant's health. Buy a cheap pump up sprayer or use an old rinsed out Windex sprayer and use about 1 tsp/5ml per USgallon of most potassium silicate additives to spray with. It's worked for me with one application to get rid of PM.
With all those plants you have I would invest in a decent sized plant sprayer with a spray wand so you can get under the leaves as you spray. Spray when you can run the exhaust fan and have as much airflow as possible. Wear masks as appropriate!
Adding panels will not help to reduce heat.

Exhaust fan and air conditioning? No other way around it.

That's what I used at the time was Rhino. I have a 500ml/820g bottle of just Potassium Silicate from CannaMax Labs that cost me $15 5 years ago and I've yet to use.
As far as I can tell from application recommendations is this stuff is 4X as strong as Rhino. When I used Rhino to combat PM I used 1ml/L so with this stuff I should use 0.25ml/L. I don't think that it's all that critical but aim for the middle. lol
The main thing is to cover the leaf surface with a high pH substance as PM hates that. One drop/L of Blue Dawn dish soap will help any spray stick smoothly over the leaf surface. Great to use with foliar sprays of any kind and even for soil drenches.

shit ton of fans and better exhaust.

Reduce the amount of bends you have in your exhaust duct. You are cutting air flow drastically with every right angle.
