I mix my nutrients as a concentrate and store it in a quart jar in the fridge.
When it's time to water, which is established by pot size/and dry weight w/soil, I set the pots on a rack that drains into another reservoir. Each plant gets 1/4 the volume of the pot. It almost always drains out the bottom, about 10 minutes later they get another 1/4 pot volume, some drains but most is retained in the pot.
