Looking for help fungus?

I'm 2 weeks into flowering and now all 7 of my plants are starting to deteoriotate looks like mice or some bugs are eating them but have neither guessing has to be some sort of fungus have been treating soil with peroxide and foliar spraying with weak peroxide solution past 2 days just wanting to find someone who knows what this is can add more pictures all 7 are different strains plants look fine besides the stems being tore up

Don't know. I would hit it with a silica spray then come back with a kelp spray every couple of days a few times and wait and see what happens.


and to strong of peroxide on you roots can burn sensitive root hairs.
