Bio Vega and Bio Flores from Bio Canna, or Organic Grow and Organic Bloom from B.A.C.
Have used both for years with excellent results.
Feeding schedules are googleable.
With soil it is plain water/plain water/feed/plain water/plain water/feed etc.
With autos, half strength is usually plenty strong enough.
Adding some type of mycorrhizae to whichever grow method you use will pay off handsomely, they are THE wonder ingredient!
