Hello newhydro16,
I grew my radishes with the verti gro
nutrients. You can adjust the flora series nutrients as needed. If you want to go heavier on the bloom you can try mixing them like
5 ml Gro
10 ml Micro
15 ml Bloom
That's a typical ratio for flowering/fruiting plants.
P.S.
Don't let the radish
bulbs get to big, they get tough and woody the bigger they get.
