How much H2O2 in DWC?

Hi everyone!

I'm starting a new DWC grow (5g buckets filled with 4g of water) and heard a lot about using H2O2 as a preventive method.
I purchased one 29% and back in the bottle says to use 4ml per gallon but I want to go easy with it. so I'm thinking to go with 1ml maybe 2ml per gallon. What you guys think? I Will change de res every week.

My system is very similar and this guy use just 4 drops every reservoir change.

I want to go as simple as him, I will use Dyna-gro nutrients (just Grow, Bloom and protekt.)
He also add CalMag but I think that's because he is using RO water. I'm going with 55ppm tap water.

Use foliar pro by dyna instead of grow bloom, im having way better results
cal mag is needed when using with coco, but using other mediums the dyna gro foliar has enough in it

I'm going with the Homebrewer formula, grow for veg and a mix of grow and bloom for flower. 40/60% maybe 50/50, saw great results.
Lot of people use foliar and I also saw great results with it but I'll stick with I purchased for now. I live in Brazil and here we don't have lot of Hydroponics stores, and when we have its 4 times more expensive, so I buy everything on ebay and it takes 40 days or more to arrive in my house. Maybe a can try foliar pro on the next time.

Thank you man
