either thick or not at all
I'm just asking if the aerobic bacteria on the pythium are ok
and I would like to know if this rust on the leaves is from pythium
and secondly, it's my business if 56 or 100, and if it eats you, nobody forbids you

Root rot, what ph you running to get that brilliant yellow? And necro spots, or is that from lights? Low ph if leaf stems are red, then yellowing leaves with purple or brown around the edges then the necro spots show up and then you ask whats wrong? Low ph is my guess.

Mycorhyzae helps my root rot, but l put in promix over losing in dwc. Or any rwdc whatever, calibrate your ph meter and feed at 6.4ph

Lactic acid bacterium is acidic but kills off bad microbes well.
