bug problem?

I checked my plants last night and they all were fine, I wake up this morning and it looks like something chowed down on one of my plants, but after an inspection i found no trace of any bug,,, I had a catipiller problem with a tomato plant in my garden, so i tossed it just in case it was attracting shit to my dope, but there were no cattipillers on it like the tomato plant, does anyone know what i should do? i sprayed it with and organic pesticide, i dont want any of my other plants getting infected please help!

same thing with me..fine last night and now my plant is chewed on and bent

i no i am just a noob on this forum but your problem is fungus gnats they lay there larvea on the bottom of leaves and when they hatch they chew leaves and become full gnats within a day thats y you dont find ne thing.... i no because i had the same problem and also they lay larvea in the soil too so you might wanna check tht out too... you can get rid of them using your piss or use somthing storebought like B and G formula hope i was a help
