Shrooms and Strange spots on the leafs

Hello everyone!
I know people say read other threads before posting and i have been doing that and some research for a while, but i just cant find out what the problem is. I have gone to my local hydro store and even talked to some other growers but no one has ever had the problem i have.

So it starts.

I have a Sensi star 2 that i have in veg, been there for 4 weeks. I use coco soil, and coco nutrients. As a lamp i have an Enviro Gro Blanc froud Cfl 250w. I used to foilar feed them with 24ml of both A and B ( i just found out that foliar feeding them with that amount nutrient is to high). I usually feed them every 3 day with the same amount nutrient as i use in the foilar.
So 3 days ago i suddenly noticed some small brown shrooms poped up in the veg tent on one of my plants. I removed them and they were very easy to move, cause they were just on the top of the soil, not with roots down in the soil if that makes any sense. So after removing them, i noticed the next day there were several small shrooms on the soil. After reading about shrooms on plants, i found out it was a good thing if the plant didnt look sick. Then i started to wonder if my plant did actually do look healthy and now im having some doubts since there are lots of small spots on the leafs.

So my question is should i remove the shrooms?
Should i use anti shroom spray or should i just throw the plant?
Can i clone the tops of the shroom infected plant or is it pointless? ( The spots are not on the top, just on the lower leafs?
Is my plant healthy and maybe thespots just came from using to much nutrient in the foliar spray?

Thanks for help in advance, wish i could reward anyone who could help me.
Take care

Those spots on the leaves look like insect damage to me. I wouldn't worry about the shrooms.

3 differnt mediums is causing ph skews. Imo. Could be early stage of blight fungi

Thanks for helping out guys, i really appreciate it.

So it looks like i got Fungus Gnats and they are eating the leafs and placing larves in the soil.
After reading online i found out i could buy some yellow stickers to get the adults to stick and to mix some bacillus thuringiensis in the soil to take out the larves. So after reading this i got a little bit more calm bur one of my other grow buddies told me that i should throw them away and sterilize the veg tent. So know im confused, should i throw them away or try to save them with bacillus thuringiensis and yellow stickers?

fungus gnats dont eat leaves their larvae eat roots, if it is pests i would say Thrips
Could be MG deficiency, but its hard to tell from those pics what it is

Fungus gnats are more of nuisance than a real problem unless you let them get way out of hand. bobtokes is right, they only eat the roots and can usually only kill seedlings or clones. You can just buy some mosquito dunks, crumble a bit up and sprinkle a bit into the top of your pots. They'll be gone in a week or two. The adults aren't a problem.

Bubble barley bails in buckect of water...add alfalfa meal for supercharge tea. Stimulate ur bacillus n growth

haha I had four or five inch (seemed like anywho) inky caps over night
