Reading the Wiki article, there's a statement that the "traditional" European compost tea (minus all the weird equipment some people use nowadays) was 1 part compost to 3 - 9 parts water, let steep for 3 to 24 days, strain out the compost and use the water as fertilizer or spray.
1 to 1 would make more of a slurry than a spray, it seems to me.
Whenever I mix worm "tea," I just put a little into the watering can and add water. The mix is light tea colored. I water the plants. I haven't spray the foliage yet with any of this stuff; by the time I've gone to the worm bin, filled the watering can, etc., I just want to feed the plants.
Maybe next season?
