H202 frequincy

Hey guys i have been doing a h202 flush of my hydroponic ebb and flow system every week when i change the barrel. Im currently in week 3 of flower about to change foe the fourth week. Ive been doing it to try and be proactive on root rot and just general maintanice. I have seen no problems and my system is staying clean. My question is does this pose a future problem? Does this kill my root biome network, is it killing my healthy root bacteria. And is it safe or even nessecary in this late of flower. And can a hydro system really even have that much of a root biome?

Just use it start to finish, many grows on google will show you how. It dosent hurt roots but kills everything organic so no nasties can live in your res. You either go sterile res with h202 or use beneis non sterile to combat the bad stuff. H202 is awesome, cleans my rockwool right up
