Ok, I've already found the answers to some of my questions. I'll post them here in case I got the wrong answer ;-)

1. I think tap water WILL be ok to use so long as I have an EC meter and watch the pH. I'll still have to watch the pH using RO water, but the PPM should be neutral, and make it so I can just do what the directions tell me to do without worrying too much about over ferting. Is that correct?

2. I'm still not sure about this. Does the pH up/down and the EC mixture change quickly? That is, do I NEED 24 hours to let the pH/nutes mix together or can I do this within the hour I'm planning on changing out the reservoir?

3. Apparently, some nutrients are "all in one", others require additional or micro nutrients. Bottom line, follow the feeding schedule and the recommended nutes.

4. Still unclear on this question, I would appreciate your input.

5. Also not sure on this one.

6. I'm assuming that there's a negligent difference here, if at all.

7. From what I have read, there's no such thing as too many bubbles, and two bubble stones will be fine.

Again, thanks for any input.
