Progress report questions??

This is the end of my 1st week of growing. I change my nutes every Saturday, so I am officially in my 2nd week. I would like to know what everyone thinks, and any advice on how they look.

I have been told to use 3% h202 on the 3rd day after nuts change, one tsp per gallon. How ofter should I add it, once every nutes change or every 2 or 3 days?

Also the bigger plant droops every time I turn the lights off, stands back up as soon as the lights go back on. Any advice or is it not a problem.

The plants look great man. I can't offer you advise on h2o2 because i'm just learning hydro basics too, but the leaves lifting and dropping is a natural reaction. It's just the plant enjoying the light, and then resting at night.
