OK, I'e been reading the archives and based on the Non CO2 method thread from April 2005, this is what I've come up with so far.

I have a new 46 gal bowfront tank, heavily planted with swords, anubias, water wisteria, wendts, etc. I do want to add some more fast growing stem plants next week. I added a bunch of mulm from my established tank and am carefully adding fish. So far the cycle looks good, although of course I'll keep an eye on it. The fish are happy and healthy. Some of the new plants I added seem to be melting. I am assuming this is from transplant shock and/or changing from emmersed to immersed growth patterns. The cuttings from my old tank look great.

Light is a 6500K, 96 watt compact fluorescent, on 9 hours a day. That's a bit high wattage, but I hope I can pull it off. I'm double-dosing Excel, no CO2. (I'll go pressurized CO2 if I absolutely have to, but Id rather not.)

I bought KNO3 and KH2PO4, based on you guys' advice. Now I need to figure out a weekly dosing schedule.

Today, Sunday, I added 2 caps Excel, and 1/4 tsp KNO3. Now what?

KNO3 1/4 tsp/week (once a week? twice? or???)
KH2PO4 1/8 tsp/week (once a week? which days?)
Excel 2 caps/day
Flourish ????
Equilibrium ????
