keeping it basic is always nice but you might also want to think about other options
Alfalfa sprouts- Sold as an animal feed, Alfalfa Pellets are an excellent nitrogen source (up to 5%). Also contains trace minerals and triacontanol, a naturally occurring plant growth promoter, which has been shown to improve the growth and yield of many crops.(most likely your local pet food store sells it as rabbit food for cheap!)
Liquid Karma - If you are looking for just one thing to add to compost tea, Liquid Karma is the one.It is good for every stage of growth and will definately increase branching points, fruit and flower sets and overall yield by as much as 30% . Liquid Karma Chelates micronutrients through amino and fulvic acids, and shuttles them into plant cells, increasing metabolic rates and conserves

http://www.planetnatural.com has just about everything under the sun you can use for tea's
I've heard it called benny tea, compost tea, beneficial compost tea, and i'm sure there are many other names for it. This might help your search for new recipes.
another place I have found useful in creating compost tea recipe's is youtube
from what i understand these products only have to be present to be useful. I also think that 2 cups of wormcastings might be a little over board, you might think about using 1 cup and possibly adding either rabbit food or mexican bat guano probably only need 1/2 cup of either or both and with the liquid nuit additives i generally figure 1 tbs. per gallon of water.
When you are making the tea you are creating a small world or possibly a lake of microbes that double every 7 minutes with living organisims. So 30 hours should definately be a decent amount of time.
My absolute favorite fact about the tea is pH is no longer any worries throw away those $300 meter's because you don't need them anymore.
Your grow however is looking very good keep up the good work!
