Give it another week before you hit them with this recipe. I have no way of knowing exactly how to water your plants because of all the variables in container sizes and genetics. This could easily do all your plants if their in the 1 foot to 1 1/2 feet range just cut with ever how much it would take to water all your plants. Also a good water source is needed and if you are starting with tap water you might need to bubble it alone first before adding the organics. The bubbles do a number of good things beyond adding O2 to the water it brings the organics to life so to speak.
