My garden was so bushy, but this is the 4th time I’ve dealt with root rot killing my herbs. I do maintenance every 7-12 days depending when water runs low. I put nutrients when I clean tank. I keep PH between 5.5-6.5 like I’ve seen a few posts recommend. Ive tried hydrogen peroxide, I’m not sure if I’m putting too much or too little for my 3L tank. Is it just a one time hydrogen peroxide treatment or do i have to do it daily? My roots are literally disintegrating. It looks like my sage, dill & cilantro are suffering the most. Should I restart with them or am I able to save them?

Are these flowers budding on my red bell pepper? 😍 I know it's silly, but I'm so excited for them!
