You need some Hydroguard bro. It will save your roots. H2O2 will destroy every microbes you have in the bucket and actually it will destroy your roots much faster if they were fully depending their symbiotic relationship with the microbes. No H2O2 ever again.
Try Hydroguard. Also how are you cooling your bucket? Do you have light leak somewhere?
Also how much air are you pumping ?
