Na, this time round I'm plain old pot watering, no bubbling of the run-off... Yeah, It does look like gunk down there but its not, its camera fx due to white balancing. It does look freaky though, but I assure you there is no algae down there. The roots just keep on growing!! Even though there is like 0.05mm of run-off in the tray, everyday there is more and more and more spread. I am starting to get worried I may run into trouble like root rot or something. What should I do here, raise the pots? Trim the roots?
I've upped the EC to 1.0 as the TD's as complaining for food. I've also introduced Liquid Silicon at 0.5ml/L and rhizotonic down to 2ml/L, A&B at 1ml/L, Sensisym 2ml/L, pH 5.8
