The Medium is Sunshine #1 Tranoble used Sunshine #4 it has 5% more perlite which I added a bit more then 5%... The feet seem happy so far. I hit them w/ a microfoil spray twice and 3 beds are now good... I checked the PH in all beds. The 3 good beds are at 6.5-6.7. Now the bad one is @ 7.0 same feeding schedule same medium the only difference is the foil spraying. I will post up a PIC 2morrow.. Thanks STINK GL
