so the drama still keeps going lol so after about a week my roots started to get this mean brown slim all over them come down to uptake it coated the roots that bad they could not breath and the plants started to wilt so 3 days ago i decided to do some home surgery i cut the seedlings clean out the rock wool cube and cut every bit of brown root off lucky me the core root ball had not been affected yet so i trimmed away all the brown root mass to the ball risky stuff 50/50 if they live or die drained the rez for a full clean and dropped 4 mls per ltr or rhizo and about 7 mls or nutes to 30 ltrs of water closed the tent up and hoped for the best went into still very droopy but hey we have new growth also a set of new roots so i say about another week or so we are gunna bounce back into action so in the end i ditched the uptake in the bin
