These are 5 week old clones. Under quantum board 210 watt. 2x4 tent I want to scrog. Are these looking healthy I see a few roots tinted brown and didn’t know if normal ? I use sensi grow in 15 gallon reserve. Each 3gallon bucket has a stone. I add a jug of ice daily to keep temp under 72. These are blue cheese clones. I need to top at about ten inches tall but not sure where to do it so I added pics. Any advice and help would be appreciated. I am hearing to dilute some peroxide and add to res but do know if needed?
1.where to top

1. How is plant and roots looking?
2. Peroxide or not?

All advice will help

I don't do hydro or clones,so I'm no help at all, other than to say to 420!

Lots of hydro growers here to answer your questions,
hopefully someone will chime in here pretty soon...
Good luck with your grow!

Also look at new grow tips they curl? Is this a worry? Just started
