Fro5tyanswered grow question 2 years ago So the thing is, they don't stink. (Points to not being rot). But I do have mag deficiency, droopy leafs and stunned growth.
I'm going to pump my water out of the RDWC and into my tank. Add again 0.75ml/L h2o2 of 12%, see if pH stabilzed and then see next week.
Thank you all for the help, and opinions!
