good luck mate -
in your first post you mentioned your roots looked and smelled healthy. so that changed quickly? those dont look so sporty.
Whenever, in the past, my plants stalled badly, it has always been related to my roots looking unhealthy. I usually would blame it on some bacteria or whatever getting into the roots. Once it happened, they never fully recover. But it sounds like you are doing the right things. I would change out the res very frequently, once your roots go brown, if you hope to recover you will really need to keep root zone temps super low. roots will grow better with the temp too low than they will with contaminations. how cool can you get them?
