See this that is what I theorized but wasn't sure about, but the bacteria no matter how low in numbers should increase eventually if temps/food is available and correct. Do you know if there's anything in particular I can do to give the bennies more food? Or is the food naturally provided via your roots and other microbes in the water? Sorry for the questions, it's just that my pH has been dropping very fast and even though I am applying Hydroguard and roots look ok besides infected roots from before it still worries me. Mostly because the root ball is soo massive (veggied too long, roots almost too big for the bucket), I can't check all roots properly.
