What are the differences? When is a good time to use one or the other? I here people talk of Flourish but rerely is the trace mentioned. I have a 10 gal, 3 wpg with indica, repens, nummilaria, Bacopa, crypts and a little difformis, java ferm and Didiplis. Dose currently 10 k(from K2SO4) kno3 as needed for N, will deal with P in a couple days when my goodies arrive, DIY co2 and a little Sera florena for iron and traces. Any recomendations for using Florish and trace I also battle small amounts of BGA especially towards the end of the week as my NO3 gets near 10ppm. My plants don't seem difficient really but they certainly are not growing like they used to. I assume traces are missing. Any ideas?
