Question about my line of Nutrients and DWC

The layer of foam you are talking about comes from the Power Roots and Pure Zym. These are mostly organic. The foam layer is therefore bacterial life, in short. These bacteria do no harm to the plant. In fact, in many cases it turns out well because a bacterial conversion process has started.

However, it can harm some systems. When you use a recirculating system, it can build up. A bacterial film can form which can cause blockages or a bad smell. It should also not choke the roots of oxygen.

for RDW or a DWC I often recommend not to give Power Roots, Pure Zym & Sugar Royal every time, but only 2 days before changing the tank.

I use Plagron 100% hydro for my DWC setup, I'm currently running it dry according to their shedule, just to see.

when I add the root stimulator, I get stained water (the liquid is black) and white foam with some brown foam.
Their website says the line is fine for DWC, my pH and EC are also the same.
Ive added a picture of the ingredients of the Plagrons Power Roots, Its got seaweed extract and other organics in it.
is this normal/ something to worry about?

Theres no light leaks in my bubble bucket, and the temperatures are below 75

I dont have acces to hydroguard, but I did find this http://www.420hydroponics.eu/rootshoot-bascilius/ which appears to be similar?
