Advanced Fungus gnat Suppresssant

So i havent caught any on traps yet and i sprinkled DE on top of soil as well as giving them a thorough dry out to see if they bounce back, leaves are yellowing and turning brown pretty bad, so i was wondering if they are root bound could that be the cause also? Tips aren't burned from nutes so im slowly upping dosage of dynagro foliage pro, i think i am going to experiment a little bit and transplant one into a bigger pot to see if it helps, i think current pots are 3 gallon, i will post pics when lights go out

Good lord this has been a rough road for me!!!!

They did not work for me and I think they made my pot taste peppery.

The thing that I have been doing is using a Utility lighter to burn their asses and the larva. It works better than anything with fans.
