I think my plant was overwatered

Fungus gnats can effect hydro too , fuckers are persistant, they like anything wet and also will lay eggs in saucers that have not been cleared of run off .

Ya that’s why I was questioning misting inviting them. I really doubt misting the leaves would make it worse or even be the cause. Yup hate em lol.

lightly misting leaves won't cause fungus gnats. letting the tops of your pots stay wet for more than 24 hours at a time will be an open door for them.
misting a plant doesn't really do much for it, though. there is no mechanism for a plant to absorb water through the tops of its leaves, some few nutrients will penetrate on contact, but the water will bead up and run off, or evaporate and leave a small stain from whatever was dissolved in it. it does raise the humidity in the area, which will make the plant not need to transpire as much, so it will grow slower, since it's not drawing any nutrients up through it's root system with the water it doesn't need, since you raised the rh

I use to mist and foiler feed and never saw any detrimental effects, actually thought the plants looked great (personal bias I’m sure lol). I haven’t done it in a bit (to lazy I guess lol) and the plants still look great for the most part. My rooms tend to be on the dry side so extra humidity is not an issue and maybe a help). As for the gnats, they tended to live under the surface and would come out when I watered by the hundreds. I’m about to switch back to a coco based grow I’m thinking, so we’ll see if the bastards come back :(.
