The easiest thing for the OP would likely be Fire Fox Ocean Forest soil, water/fed with Blumats. No nutes for the first month, then start on a simple one-part nute fed at around 1EC for another month to veg the plant out. Transplant to larger container at that point, with more FFOF potting mix; and drop feed to 0.8 EC for one week. At the end of the week, flip to 12/12, and increase EC to 1.0. After 2-weeks 12/12 increase EC to 1.2. After 4-weeks 12/12 increase EC to 1.3, then feed water only for the last 10-days of bud ripening. Shouldn't be able to overwater that way, and shouldn't ever need to flush. No multiple part nute programs, no ph required, just a decent 1-part like MegaCrop or Veg+Bloom.
