I'm helping a friend start up an ebb and gro with sure to grow inserts. Anyway we made a modd to lift the pots an inch and a half to keep water from standing in pots. 2 young ones died so we lowered it back. water level I guess. kind of looks like your leaf when they died.

So all the same except room. His are not growing as fast as we thought so we went to 8 feeds a day and things are looking better the past week. It's very hard to find any info or anyone using STG inserts with an EBB&GRO.

If it doesn't look better soon bump your feeds back up. STG says that since the STG does not wick that growers can up the feed times to bring more nutes to the roots.
