I haven't had much trouble with blow overs. I don't use any type of recirculation. I feed them in the mornings with a very weak solution, only about 10 ounces or so of solution, it's not enough to flow out of the drainage holes at that point. In the afternoon, I give them a dose of fresh water, just enough so that the reservoir fills and trickles out through the drain holes. From tending them daily, you get a feel for how much water is needed, so there's not a lot of waste. The watering/feeding chores only takes 10-15 minutes a day, but I only grow about 50-70 plants at a time.. This system would be impractical for large grows.
I'm currently using Hydroponic Special soluble fertilizer, mfg. by Southern Ag. mixed with magnesium sulfate and calcium nitrate. 4 parts hydro special, 1 part magnesium sulfate and 1 part calcium nitrate. I mix about 2 tbs. of this mix in 5 gallons of water. This is a little on the weak side, you could mix it a little stronger if you think the plants need it, but not too much, with fertilizer, less is better than too much.
