Afghani 45 day hash

I have an Afghani plant its almost a month old, and I started to notice the plant little by little tilting I have to tie it up in order to keep it up..Some of the leaves are droopy and I opened the top and my roots are brown seems like root rot, what can I do to fix the problem...Any suggestions will help...Thanks

Hydrogen Peroxide (h202) will help with preventing root rot. But it may or may not help with already rotting roots.

Use 2tsp per gallon of 50% or 150ml per gallon of 3% in your reservoir.
