watering techniques

I have 5 mother plants 2.5 feet high in 5 gallon felt pots.im using advanced nutrients sensi ab. How many mls per liter should I use and approximately how many liters of water per plant should I feed?

SO, I have started what I call "micro-watering" or "micro-feeding". I can't seem to find anything on it, but the plants seem to love it, and it has cut my water usage drastically. So basically, what I have been doing, is giving 3 full turkey basters of water, which equals to about 4.5 ounces...
