Changed out the water 2 days ago. Forgot the hydroguard. Pic says it better than I could =(

oh boy, cooked roots / root rot. What does the hydrogaurd do? I've never grown proper hydro before.

Yep I've had trouble with temperature too! Hydroguard, AFAIK, is good bacteria that out-competes bad bacteria.
