While in the #1's....nothing from kit required. Upon transplanting ..start with a Transplant Drench...then plain water....then again with plain water...then a GE Drench...then plain water....then plain water W/1/4 Transplant...then another Transplant Drench....repeat these steps. Follow kit instructions for amounts of Drenches. After plants get some size only one plain water between Drenches . Alternate GE and Transplant Drenches all thru veg. Hope this helps.
