Root problems Help please. Need answers and advice
Alright so I set up an aeroponic system and it works okay. My plants can stay alive and can grow roots. Only 1 problem, I have a brown algae problem. So I went to my local hydro store and he advised me to throw a very small amount of physan 20 into water only and let it flush my plants and system over night and it would rid the algae and and what not .
Well I did that and it turned my roots a gross brown color and now they look unpleasant as if they were dying but the plants are still growing and haven't died.
Why did the physan turn my roots brown??
Also I don't get large root masses I get like a string of rights straight down and that's it why is that. when I see other people grow hydro roots come out everywhere, when I grow they come out in 1 spot only.
