I had to leave for two days and needless to say my ph went crazy low and the temps were crazy hot. I came back and changed water and nutes. Roots are dark colored and I also notice at the main stem at the top of the grow rocks it looks like it rotting.

What can I do to prevent further rotting????

Thank you in advance.
