Gnats are attracted to moist rich soil. Get some diatomaceous earth to sprinkle on top of the soil to kill the larvae. Get sticky yellow traps for the flyin fuckers. Easy to control them; they are more annoying than anything else but can get all stuck in the buds if left unchecked. Nobody want dead bugs in their weed...

Would spraying the the top of the medium with neem oil and water do the same as that?

I would say elevate your pots and make sure you're not overwatering, but those pots looks hella dry. Is that coco and perlite? If so that's way too dry. You want to water evenly so that the roots can spread out and stay wet.

What size pots are they. 7 gallon if so should be watering every 5 days or so.

Supposed to be 5 gal but they are not the same height as 5 gallon buckets so I’d say 3 gallon fabric pots

Yes that works. I've done it. They don't like neem and it won't hurt your plants. Neem oil drenches are used by many for that exact issue.

Watering every 3 days is a good recipe for salt buildup. It's clearly bone dry at the edges. Cutting back on feeding due to gnats isn't the correct solution to the problem. GL

So I shouldn’t be watering every three days like the bag of coco says on the back ?

You're going to do more harm letting the coco dry out than anything some fungus gnats are going to do. Gnats are more of a nuisance than anything.

Ok another dumb question then. Will a little soil drench with neem oil kill the mycorrhizae I’ve just put in a about a week ago???

No. Coco should be feed at least daily to significant runoff. It's not soil.

Damn hopefully I don’t kill them I will go back to daily watering

I used to keep runoff but I read that’s what’s causing the gnat problem so I cut back

A good 10-20% runoff too

It won't kill them but lack of watering in coco can lead to salt buildups and EC spiking in the medium. It's generally just unhealthy for the plants.

Don't let the runoff be in contact with the pots and dispose of it immediately after you finish watering.

No. People use neem meal as an amendment in organic soil all the time.
