How often have you been watering? What kind of soil? Nutes?

i been letting her dry out in between waterings the soil is just basic potting mix and i been using miracle grow i teaspoon per gallon every 7 days

my buddy gave me some advice today and said to flush it then add nutes and ph the soil again and it should help "simple" i said to myself so i went ahead and started flushing well when i did i noticed a bunch of little black bugs coming out of the dirt i got scared and started googling and found out the were fungus gnats and it said to get rid of them use peroxide so i dunked those little bastards in water/peroxide mix and let it fiz waited a couple minutes then finished flushing it i did it till the water ran out clear then phd my water to 6.6 using apple cidar then i fed with miracle grow 1 teaspoon in a gallon and added a teaspoon of peroxide so now im waiting to see what happens what do yall think?

If you've got gnats you've been keeping the soil too moist. Gnats cannot survive in drier environments. Your other option is to add a layer of diatomaceous earth to the topsoil. This is literally like living in an environment where everything is broken glass. That is. If you're gnat larvae.

I'm thinking da miracle grow nutes, I don't trust dem with cannabis

Yeah I've heard miracle gro is kind of a no no. Not the right mix for growing cannabis.
