Finished week 7 no problems, one last CalMag and one last feed with Herculean Harvest, really smelling strong, no issues. Getting really frosty on Recipe420#1, R420#2 kept her green throughout and the FFOF phosphorus deficiency was caught in time. Last feed week and now just plan on plain water until she finishes up.
@Thaiclee, cover the top soil to keep it moist and the microbial life active, helps with pest prevention as well. I've used organic rice hulls in the past for the silica but there is trace amounts of arsenic with rice hulls so I switched to hay.
