Is this fertilizer ok?

[jreidsma]

I've only been watering everything with fertilizer once a month, maybe for my orchids I need to fertilize everything more.

So maybe for my orchids and faster growing plants that need more fertilizer I will do you like said and water them more often with the fertilizer, but at a lower strength. Maybe water once with it, then one time without, alternating so nothing builds up.

So which fertilizer should I use for all my orchids? the 30-10-10, the 7-9-5, or the 17-9-26? It sounds like they all would work, but I don't know which would be best. I kind of like the 7-9-5 because it is more well rounded and the 17-9-26 because it sounds like it promotes blooms more that the other two and it is for epiphytic plants and more sensitive plants.
