Did you spill anything on the leaves ?

Maybe post some environmentals like temp humidity. Some equipment and food you’re using. Is your humidity low ?

A picture of the overall plant may be helpful too

I do have a thread posted under my name and it's documented on what it is

Everything is in a 4x4 tent under a $660 w spider farm LED they are in a two and a half gallon air pots I'll post a picture of the nutrients I use

I'm not sure about the temperature and humidity I don't have a thermometer or dehumidifier or humidifier. I haven't poured water on top of them it's just straight into the soil All these burnt marks on the upper leaves in Middle leafs where it doesn't get water. It is on all the plants in the room
The plants are too crowded.
That's most likely leaf septoria or something close to it, a bacterial infection that goes with lack of air circulation.
I'd say select the strongest branches and prune the rest. Which will also get rid of a lot of the infected leaves.

You need to be aware of the environmentals - temperature & humidity especially - to diagnose what's going on. A temp/humidity meter is v cheap.
If this a compost/living soil grow, then pH is slightly less critical, but I'd still want to know what I was putting in. My grows improved massively once I got on top of temp/humidity/pH and EC.

Looks like LIght burn to me.

This is very good advice, far too often we fail to properly observe and check every possible detail before making a diagnosis.
Nute prob starts at the top or bottom
Light intensity starts at the top or inside
And bug damage is randomly scattered
Examine leaves undersides with a 60x loupe
Did you spill nutes or anthing else on leaves?
Overall they look pretty healthy they gonna flip to flower or moms ?

I make the same batch of nutrients every time. I'm using Foop nutrients with cyco nutrients silica and doctor repair I have hydrozyme great white and cal mag it's rare that I put them all together but I usually split up the nutrients and I try to keep the pH between 6.2 and 6.6. I'm going out flipping to flower this week

I do have a friend that helps water the plants when I'm not there so maybe he's pouring it on the plant itself. He does not want to learn how to pH so he just gives it straight water
It's leaf septoria. Notice the transition zone where the fungi are consuming the green tissue.
Either way, it's caused by lack of airflow. And the plants need more nitrogen.
Leaf Septoria
Notice the parchment looking part, surrounded by a pale transitional zone, where the fungus is consuming the green material.

Interesting point from their website: "It may also show up in nitrogen deficient plants."
Recommendation
1. Prune the weakest branches, branches growing inward and prune back 1/3 of the bottom foliage.
2. Flip them into flower.
3. Give them more nitrogen.

Sizing up Septoria
From: Studies in Mycology(Vol. 75)pg24/330 morphology
Chlorosis is simply another term for yellowing. You are most likely to come across the term in descriptions of nutrient deficiencies or plant viruses (another term used commonly in such descriptions is necrosis, meaning cell or tissue death).
Definitely prune it out and remove it from grow area, no reason why these should not finish as intended
get you a good 60x loupe and microscopes are so cheap now days, pests are small mostly 
Always rule out everything before dismissing it as a fluke spill,

I went to go check on the girls and I found white powdery mildew. I looked it up online and that is what it seems like what it is The solution to fixing this they said to cut off the leaves and sprayed the plant with water mix with milk has anybody experienced this or know anything about it to help out thank you
That's not powdery mildew.
That's too much and the wrong nutrients. The leaves are burnt/crispy, and the plants shows a little nitrogen deficiency.
It is best to know what the nutrients and soil are.
- Medium used
- Nutrients used
- pH and EC or PPM of both medium and liquid nutrients would be helpful

Don't spray milk on it friend. You need a magnifier loop and get a good look at the troubled spots. If it is fuzzy like hairs it's probably mold.
