Is this Root Rot damage?

[lilywhite]

Hi All,
Could anyone advise? 3 days ago disaster struck, i had a few hours where the temp in my growspace went up to 36c leaves were badly damaged all over plant, a copper/brown colour. I have the temp under control now. I removed most of the damaged leaves and some of the damaged budsites and applied hydrogen peroxide to the soil. There is some small signs of renewed growth but its in the lap of the ganja gods now. I would like to get some opinions so I can learn from the experience.

Hiya lilywhite.
Did it have any of that leaf damage before the heat spike?

Hi Listersmeghead, No all the leaves were ok before heat spike. I was very surprised how quickly it happened, literally within a few hours

Wow, that is a big diference, the fact it's still alive is a bonus. You're doing all you can do already, normal peramiters and see how she responds.

I've seen some use of super thrive in cases like this, to give it a little boost.
