Fungus gnats cause yellowing leaves?

I hear yellow leaves are also a nitrogen deficiency

Got some gnats in my last 5 or 6 bags of soil I picked up. Roots organic original. Put up some yellow sticky traps and got a bunch of adults caught on them. Was looking through info on how to kill the larvae as I don't want them eating my roots. I do use caps tea mix once a week....i may just not dilute the tea as much and see if that works.

Also read you can use one part pure 3% hydrogen peroxide with four parts water and that will kill them in the soil. Has anyone had any experience with this?

...you really don't need to do anything like that, either follow the strategy i posted above or just go with the sticky tapes, unless you have a HUGE infestation most of the flyers, aka egg layers, will have been caught within 2 weeks while most of the egg's will have hatched and become flyers, hopefully caught before they themselves can lay more eggs.

...obviously the sooner you put the traps in and the more of them you use the faster this will happen.
