Thoughts on fertilizer.

[newbieatwork]

Ok... I've tried to understand the whole ideal of this thread but still kinda clueless, pherhaps I just got interest in orchids and went out and bought a phal without thinking how much work it is involve to keep it alive and healthy. I'm using 7-8-6 formulation (1 teas mix with one gallon of water) once a week to soak my orchids as my watering method.

My question to the pros here...

Will this formulation adequate enough to keep the orchid alive and rebloom? The water is just tap. I don't know what RO is (Reverse Osmosis?) Please tell as much info as possible. I want to do it right. I've read many other websites on how to take care of the chids but very limited information and many are the same info.

When I finish soaking the plant in the container with the mix fertilizer and water. Can I reuse the water a week later or can i use it to mist it daily?

TIA,
