Mitch-
Teas are also a GREAT idea. However, I would amend the soil you're using with EWC as well as the guanos. There are a million and one recipes for mixing in which ratios... Find one that most closely resembles the starting soil you're working with. If you're using the native soil, dug out of the ground, there really is no way of knowing its contents, etc. Err on the weak side of any soil amendments. An ongoing Tea regimen (every 2 weeks if you can) would help tremendously. If you can't get out there to use Teas, then mixing the soil with some good amendments will help to cover that gap somewhat. I know you're planning to use your indoor feeding program, keep a close eye on how there plants respond to that, as the environmental variables present in an outdoor grow changes the plants needs and requirements and is not directly analogous to an indoor grow.
At any rate, seeing what you're doing here is really inspiring me to get back outside and stick a plant here, and plant there, a plant everywhere.
