1st setup since 2009! Looking for pointers...

Just started getting back into this (you can see my last grow on here and my post was in 2009) and setup a drip system w/ misters in the grow buckets with a separate reservoir. About three weeks into it and I measure PH (6.5) and ppm (~800 using Lotus Nutrients), I was also adding hydrogen peroxide daily but 4 days ago, switched to using Hydroguard (I hear this maybe better to prevent bad bacteria or algae from growing). Anything that i can do differently, tweek, add or change? Any tips would be helpful!

I recommend running a sterile system with pool shock..
