Bane of hydroponics, root rot help

I don't think that's right. Cyan means blue or blue-green. Bacteria and algae aren't the same. There's brown algae, green, even clear as far as I know. But cyanobacteria must be blue or blue-green. I still think the slime is algae.

Heisenberg explains it all in the first post

I read through some of that and I think Heisenberg was full of it. They say that if you have clear snot on your roots you have brown algae. This doesn't make sense as why would clear slime be called brown. Then Heisenberg says it's not algae, it's cyanobacteria, which the internet says is a blue-green algae that takes place in nature. How can Heisenberg say that something that is clear is really brown, but then not brown, it's actually blue bacteria. Heisenberg is full of shit. They plainly say it's algae of different colors, then say it's bacteria of the wrong color. Algae is called brown or clear or green based on its color or lack of color if clear. It's not hard to understand.

In the end, seems QB 240w for such small tent was too close too high power. They burnt all plants thus later causing root rot from the stress. Secret Jardin CR145, buckets for DWC taking height. Plus hanged light all-in-all seems light was around ~30cm from canopy. By far too close and too high power.
Good it turned out this way cause had Police raid over anyways...

Tuned lights down and now all good. Generally I guess learned for the future that apparently LEDs can burn with light alone without doing heat damage... It was 1.4x1.4x1.2m , so quite wide but very short...
Previously always used 2m tall ones so never had such issue before.
I have dimmer on all my lights just didn't think it'd be that needed to tune down. I guess learned hard way.
