First DWC grow with Plagron Hydro went well. Now using Canna Aqua with the same water and conditions, but roots look much worse. Both plants in the video are affected, and they are different strains. Could Canna Aqua be the cause?
In DWC the roots can turn color because of the nutrients. I’m not familiar with Canna Aqua, but if your roots aren’t slimy or smelly, the new root growth is white, and your plant growth is not affected, you’re in good shape. To be on the safe side I’d use Hydroguard to avoid any possibility of root rot to begin with. I also grow DWC.
The root system looks unhealthy. I’ve dealt with root rot like that before; in my case, Hesi PowerZyme and Hesi Root helped—provided the pH is between 5.5 and 6.5. Naturally, a 2–3W aerator should be running constantly.
Happy growing!
Eigentlich sollte das nicht so sein das sind ja beides Hydro bzw sogar extra Dünger für Medienlosen Systeme...welche Temperatur hat dein Wasser?
Benutzt du Desinfektion H2O2 etc.?
Dein Wasser wirkt Recht schaumig auf dem ersten Bild..?
Benutzt du Wurzelbooster?
Bei der Größe an Pflanze empfinde ich das Wurzelsystem als Recht mager....
