I have a light fish load in my barrel pond, so I have to add potassium
nitrate for mine. If you add a bit of potassium phosphate, they'll
all flower. Sometimes they look a touch chlorotic and then I add some
hydroponic iron/trace element fertilizer.
=======================
Do you know a good online place to buy hydroponic fertilizers? I can't
find anywhere local that sells the stuff.

Thanks.

http://www.gregwatson.com. Plantex CSM+B is great stuff and he carries
the bulk potassium nitrate and potassium phosphate.
