Okay brothers,after searching and searching,I finally found fadeds' thread on fimming,although the first fim was done at 5 nodes and things went smooth with no negative effects,only time will tell how the "extreme" fim job is gonna affect the plant,since AU is a 65-70 day strain,I'm sure just like that last AU grow,they will be more like 80-85,they will go to 40 days before they get the HPS switch,this should allow the plant to be over the shock of the fim,if there is any...okay ,Peace
