Current grow

Thought id post some pics of my current grow

I have 2 1m by 1m tents

4 soil in one
1 dwc in the other.

I have tangerine dream, dynamite, gsc and grandaddy purp in my one tent. Ive been feeding them shogun nutes along with a alg a mic foilar each week. Ive been vegging them for about 8 weeks under a mars 600 LED.

The dwc is sugar black rose. Shes been in the dwc for around 3 weeks. All shes been given is cal mag and katana roots then when the roots hit into the reservoir i added 10L of water with GHE nutes.

Im new to hydro but always wanted to give it ago. I checked my ph yday and its around 5.4 ph. My ppm is between 400-600
The sugar black is growing under a 315 lumigrow i brought a few years back. Im looking to put another 300 watt led in with it also.

I have hydrogen peroxide 11% but havent added into the reservoir yet. Im not too sure on how often to use it and also the amount?

Any tips and advice would be great

35 percent hydrogen peroxide is added at 3 ml a gallon, bennificial bacteria out preforms hydrogen peroxide though.
Looking good for a new hydro grower.

Good luck
