Weird spots on leaves

Greetings fellow growers
8 weeks , 2 autos on a 12/12 I spotted these spots on one of the plants , if u guys can help me to figure out what’s happening maybe ?
Oh and should I start cutting the big leaves ? Because they won’t let the light go all the way down to the plant ?
Feel free to ask me question if needed
Thank you :)

Along with those spots it looks like you have some cupping/clawing/distorting leaves going on. I would guess that the same problem that is causing this is also causing the spots you are seeing. I suspect that your roots could be locked out either due to incorrect ph range or too much nutes in the medium, or poor watering habits.
Give more info on the medium your growing in, feeding schedule, nutrients you use, temp/humidity. Do you ph when you water? If so what are u adjusting it to?
clipping fan leaves off during flower can be risky especially with an auto, as they are typically more prone to stress. You want to do most of your training and trimming prior or very early in flowering as this is when your plant can take stress a bit better.If you do decide to take some fan leaves off to let more light to bud sites do it slowly. Only a couple leaves at a time and give your plant a couple days of rest and see how she reacts.
 
Thanks guys for your answers :)
This is the soil I’m using , also I don’t have a ph meter , started using nutes lately like 3 weeks ago , I arrose them 2 to 3 times a week I also check if they need water before doing that . Temperature is around 28-31 degrés Celsius and humidity Is around 60/75% .
For the cutting I left the plants to handle the leaves alone so some of them went out basically alone , been using lst since week 4 , the buds started to fill up too :p
