Wouldn't worry about getting any on the foliage. I just follow the directions on the bottle. 1 teaspoon per gallon once per week, or 1/4 teaspoon per gallon at every watering. Sometimes I increase it when the plants are growing vigorously. I also sometimes use Pro-Tekt, and again, I follow the instructions on the bottle. Hope this helps.

I pre-water, then fertilize, and then lightly water again to rinse any foliage that might
have drops of the fertigation solution on it.

What type of mix are they planted in? If it is a Miracle Gro potting mix or something that has nutrients in it already, you may want to hold off on using the Foliage Pro for a month or so until those nutrients have been used up/washed out...

Just a thought.

I spoke with a very helpful person at Dyna-Gro about how much FP to use with Tomatoes because last year my tomatoes in containers were quite small. Last year I followed the directions on the bottle and only used FP. This year on the recommendation of the Dyna-Gro representative I am using FP and Mag-Pro. She said during the warmer months to use 1 tsp. per gallon of each FP and MG EACH time I water, even if it is every couple of days. I have been watering about 2 times a week for the last few weeks, and have not noticed any negative affects from over fertilizing, and my tomatoes are doing well. I have Tomatoes on every plant and just harvested my first 3 tomatoes from my Early Girl today and had BLT's for dinner this evening. I am also growing peppers but I do not think I will put more than 1 tsp. per gallon per week on them.

Did the rep give you any justification for the use of Mag-Pro?

The suggestion she gave you yields a fertilizer regimen of 11-18-10 with 2% Ca, 2.5% Mg

This is not ideal. For one thing the ratio of Mg to Ca is too high. I've read that the best results with tomatoes include a minimum mg available and in a 1:4 ratio with Ca - so you want 4x as much Ca than Mg. Here's one paper you can read for verification but there are many more: http://pubs.aic.ca/doi/pdf/10.4141/P02-140

It's not as simple as 4:1 Ca:Mg in every case but certainly that is an excessive level of Mg - not to mention the issues with the major nutrients which, to my understanding, is also not ideal.
