With that I would suggest Fat Flower or Awesome Blossoms would be fine. Fat Flower would be my choice if that is the nutrients I have.

You can mix the grow & bloom for the 2 week cycle 1 before and 1 after you switch the lights. Other then that it's a one part nutrient for the most part.

If you are using RO water then you will need CalMag Plus and you should have some florakleen on hand too to flush at the end and just incase they need it before to correct a problem.
